abstract = {Cryptography has become ubiquitous in communication technology and is considered a necessary part of information security. However, both the regulation to restrict access to cryptography, as well as practices to weaken or break encryption, are part of the States’ security policies. The United States (U.S.) regulate cryptography for export in international trade as a dual-use good. However, the regulation has been increasingly loosened and transferred to bilateral agreements with Information and Communication Technology companies. At the same time, the National Security Agency attempted to implement a government encryption standard to guarantee itself easier access to data, thus progressively expanding surveillance on non-U.S. citizens. In this paper, using comparative policy analysis, we examine the evolution of both security policies by tracing the historical development of U.S. regulation of cryptography as a dual-use good, and surveillance technologies, and practices used from the 1990s to today. We conclude that the impact of the dual-use regulation has affected the efficiency of surveillance technology, by loosening regulations only for mass communication services, thereby supporting the proliferation of surveillance intermediaries, while working on strategies to collaborate and exploit their coverage.},

abstract = {In the last decades, research has shown that both technical solutions and user perceptions are important to improve security and privacy in the digital realm. The field of ‘usable security’ already started to emerge in the mid-90s, primarily focussed on password and email security. Later on, the research field of ”usable security and privacy” evolved and broadened the aim to design concepts and tools to assist users in enhancing their behaviour with regard to both privacy and security. Nevertheless, many user interventions are not as effective as desired. Because of highly diverse usage contexts, leading to different privacy and security requirements and not always to one-size-fits-all approaches, tailorability is necessary to address this issue. Furthermore, transparency is a crucial requirement, as providing comprehensible information may counter reactance towards security interventions. This article first provides a brief history of the research field in its first quarter-century and then highlights research on the transparency and tailorability of user interventions. Based on this, this article then presents six contributions with regard to (1) privacy concerns in times of COVID-19, (2) authentication on mobile devices, (3) GDPR-compliant data management, (4) privacy notices on websites, (5) data disclosure scenarios in agriculture, as well as (6) rights under data protection law and the concrete process should data subjects want to claim those rights. This article concludes with several research directions on user-centred transparency and tailorability.},

Dass dies besonders für die Sicherheit und Vertraulichkeit nicht nur von Vorteil sein kann, sondern Nutzer*innen negativ beeinflussen kann, wird in dieser Arbeit ersichtlich. Betrachtetwerden dafür die Themengebiete Anti-Patterns, Grey Patterns und Dark-Patterns. Anti-Patterns bezeichnen wiederkehrende Lösungen für ein Konzept eines User Interfaces, die trotz guter Intention ungewünschte Nebeneffekte oder Konsequenzen haben. Dark-Patterns dagegen stellen Designentscheidungen dar, die durch Täuschung oder Ausnutzung psychischen Drucks versuchen Nutzer*innen zu Handlungen zu verleiten, von denen die Ersteller*innen des Dark-Patterns mehr profitieren als die Anwender* innen. Der Begriff Grey Patterns wird in dieser Arbeit für alle Design Patterns genutzt, die sich nicht direkt zuordnen lassen. Da es bisher kaum vergleichendeWerke und keinen Konsens zu diesen Themengebieten gibt, ist das Ziel dieser Arbeit ein grundlegendes Modell aufzustellen. Dabei wird durch die Untersuchung bestehender Literatur eine zusammenfassende Taxonomie und ein Vorgehen zur Unterscheidung von Anti-Patterns und Dark-Patterns erarbeitet, die als Grundlage für weitere Arbeiten und zur Entwicklung von Gegenmaßnahmen genutzt werden können.},

While existing approaches are mainly blackbox based, showing aggregated visualisations as one-size-fits-all nudges, personalisation turned out promising to enhance the efficacy of nudges within the high variance of users and contexts. This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

abstract = {Phishing is a prevalent cyber threat, targeting individuals and
organizations alike. Previous approaches on anti-phishing
measures have started to recognize the role of the user, who,
at the center of the target, builds the last line of defense.
However, user-oriented phishing interventions are fragmented
across a diverse research landscape, which has not been
systematized to date. This makes it challenging to gain an
overview of the various approaches taken by prior works.
In this paper, we present a taxonomy of phishing interventions
based on a systematic literature analysis. We shed light
on the diversity of existing approaches by analyzing them
with respect to the intervention type, the addressed phishing
attack vector, the time at which the intervention takes place,
and the required user interaction. Furthermore, we highlight
shortcomings and challenges emerging from both our literature
sample and prior meta-analyses, and discuss them in
the light of current movements in the field of usable security.
With this article, we hope to provide useful directions for
future works on phishing interventions.},

For instance, existing research suggests nudges for stronger passwords or safe WiFi connections. However, those nudges are often not as effective as desired. To improve their effectiveness, it is crucial to understand how people assess nudges in cybersecurity, to address potential fears and resulting reactance and to facilitate voluntary compliance. In other contexts, such as the health sector, studies have already thoroughly explored the attitude towards nudging. To address that matter in cybersecurity, we conducted a representative study in Germany (𝑁 = 1, 012), asking people about their attitude towards nudging in that specific context. Our findings reveal that 64\% rated nudging in cybersecurity as helpful, however several participants expected risks such as intentional misguidance, manipulation and data exposure as well.},

To show the impact of cyberattacks on agriculture, we present a simulation of several attacks on a ZigBee-based wireless sensor network. We conduct a delay attack, an interference attack and three different routing attacks (sinkhole, blackhole and selective forwarding attack). Those attacks are simulated using NETA with the OMNET++ framework. We will show that the security of WSN is influenced by factors like energy consumption or computation power, which can conflict with other interests like low per-unit costs.},

The goal of this work is to assess how perceived security and estimated effort of using such mechanisms, as well as the degree to which app data is considered worth protecting, influence users' choices of appropriate measures to protect app categories. Therefore, we conducted a representative study (n=1024). On the one hand, our results show that a positive correlation between perceived security and effort exists for all investigated non-biometric authentication methods. On the other hand, the study sheds light on the differences between the investigated app categories and the users' choice of the appropriate security mechanisms for the particular category. In contrast to perceived security having a positive influence on a user's preference of mechanism, a relation can hardly be identified for effort. Moreover, app data sensitivity does not seem relevant for the users' choice of security mechanism.},

Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people's views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63\% and 67\%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27\%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.},

abstract = {Obwohl Usability und Sicherheit beides relevante Anforderungen für Anwendungssysteme sind, stehen sie in einem Spannungsfeld. Sicherheit kann als Schutz vor Angriffen von außen (Security), aber auch für das sichere Funktionieren (Safety) dieser Anwendungssysteme verstanden werden. Durch die immer größere Vernetzung klassischer Safety-Domänen, wie dem Katastrophenschutz, gewinnen Security-Aspekte dort ebenfalls an Bedeutung. Die Übertragung von kritischen und vertraulichen Informationen auf mobile Endgeräte muss zugleich passwortgeschützt als auch schnell verfügbar sein; zeitintensive Authentifizierungsmechanismen können hier stören. In dieser Studie werden die Nutzung von Passwörtern vor dem Hintergrund der Abwägung von Sicherheit und Usability exploriert und Hypothesen zum Umgang mit Passwörtern aufgestellt, die im Kontext der Digitalisierung in der zivilen Sicherheit sowie mobilen und ubiquitären Geräte im Katastrophenschutz an enormer Bedeutung gewinnen.},

User-centered misinformation interventions as digital countermeasures that exert a direct influence on users represent a promising means to deal with the large amounts of information available. While an extensive body of research on this topic exists, researchers are confronted with a diverse research landscape spanning multiple disciplines. This review systematizes the landscape of user-centered misinformation interventions to facilitate knowledge transfer, identify trends, and enable informed decision-making. Over 3,700 scholarly publications were screened and a systematic literature review (N=108) was conducted. A taxonomy was derived regarding intervention design (e.g., binary label), user interaction (active or passive), and timing (e.g., post exposure to misinformation). We provide a structured overview of approaches across multiple disciplines, and derive six overarching challenges for future research.},

abstract = {In crises such as the COVID-19 pandemic, it is crucial to support users when dealing with social media content. Considering digital resilience, we propose a web app based on Social Network Analysis (SNA) to provide an overview of potentially misleading vs. non-misleading content on Twitter, which can be explored by users and enable foundational learning. The latter aims at systematically identifying thematic patterns which may be associated with misleading information. Additionally, it entails reflecting on indicators of misleading tweets which are proposed to approach classification of tweets. Paying special attention to non-expert users of social media, we conducted a two-step Think Aloud study for evaluation. While participants valued the opportunity to generate new knowledge and the diversity of the application, qualities such as equality and rapidity may be further improved. However, learning effects outweighed individual costs as all users were able to shift focus onto relevant features, such as hashtags, while readily pointing out content characteristics. Our design artifact connects to learning-oriented interventions regarding the spread of misleading information and tackles information overload by a SNA-based plug-in.},

Dass dies besonders für die Sicherheit und Vertraulichkeit nicht nur von Vorteil sein kann, sondern Nutzer*innen negativ beeinflussen kann, wird in dieser Arbeit ersichtlich. Betrachtetwerden dafür die Themengebiete Anti-Patterns, Grey Patterns und Dark-Patterns. Anti-Patterns bezeichnen wiederkehrende Lösungen für ein Konzept eines User Interfaces, die trotz guter Intention ungewünschte Nebeneffekte oder Konsequenzen haben. Dark-Patterns dagegen stellen Designentscheidungen dar, die durch Täuschung oder Ausnutzung psychischen Drucks versuchen Nutzer*innen zu Handlungen zu verleiten, von denen die Ersteller*innen des Dark-Patterns mehr profitieren als die Anwender* innen. Der Begriff Grey Patterns wird in dieser Arbeit für alle Design Patterns genutzt, die sich nicht direkt zuordnen lassen. Da es bisher kaum vergleichendeWerke und keinen Konsens zu diesen Themengebieten gibt, ist das Ziel dieser Arbeit ein grundlegendes Modell aufzustellen. Dabei wird durch die Untersuchung bestehender Literatur eine zusammenfassende Taxonomie und ein Vorgehen zur Unterscheidung von Anti-Patterns und Dark-Patterns erarbeitet, die als Grundlage für weitere Arbeiten und zur Entwicklung von Gegenmaßnahmen genutzt werden können.},

abstract = {Concise instruments to determine privacy personas – typical privacy-related user groups – are not available at present. Consequently, we aimed to identify them on a privacy knowledge–privacy behavior ratio based on a self-developed instrument. To achieve this, we conducted an item analysis (N = 820) and a confirmatory factor analysis (CFA) (N = 656) of data based on an online study with German participants. Starting with 81 items, we reduced those to an eleven-item questionnaire with the two scales privacy knowledge and privacy behavior. A subsequent cluster analysis (N = 656) revealed three distinct user groups: (1) Fundamentalists scoring high in privacy knowledge and behavior, (2) Pragmatists scoring average in privacy knowledge and behavior and (3) Unconcerned scoring low in privacy knowledge and behavior. In a closer inspection of the questionnaire, the CFAs supported the model with a close global fit based on RMSEA in a training and to a lesser extent in a cross-validation sample. Deficient local fit as well as validity and reliability coefficients well below generally accepted thresholds, however, revealed that the questionnaire in its current form cannot be considered a suitable measurement instrument for determining privacy personas. The results are discussed in terms of related persona conceptualizations, the importance of a methodologically sound investigation of corresponding privacy dimensions and our lessons learned.},

abstract = {Business collaboration in the era of digital transformation requires the exchange of operational data. Since data are hardly controllable once they have been published or shared with others, it is highly important that users are clearly informed about who has access to which data and how certain settings can prevent the disclosure of sensitive data. However, giving end users more control over their data through increased transparency could also lead to information overload. This is particularly true in the field of agriculture, where tight schedules put pressure on employees of small enterprises. We conduct an empirical prestudy with 52 German farmers to investigate current data sharing scenarios. From these insights, we derive requirements and a concept for data sharing solutions providing data flow transparency for users. To investigate the behavior of users and the effects of transparent UI controls, we evaluate a prototype with 18 persons. Our evaluation shows that farmers demand flexible and secure tools that adjust to their workflows. Also, data should be stored and processed locally, granting farmers data sovereignty. Although the controls require additional effort, the evaluated transparent controls for data disclosure are easy to use and raise user awareness.},

abstract = {The Internet of Things (IoT) is a major trend that is seen as a great opportunity to improve efficiency in many domains, including agriculture. This technology could transform the sector, improving the management and quality of agricultural operations, for example, crop farming. The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.},

abstract = {Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.},

and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

These migration movements increasingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach their targeted destination countries. Asylum seekers often use smartphones for information and communication purposes. Even though there are many positive aspects in the use of such technologies, researchers have to consider the perceived risks of this specific user group. This work aims at investigating the use of mobile information technologies by asylum seekers during their flight, especially taking privacy into account. Thus, it examines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conducting a qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results show that asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, such as surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this, this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy and trust leads to avoidance behavior, the insights of this study provide valuable information for the design of assistance apps and collaboration platforms, which appropriately address the specific needs for digital privacy in the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

abstract = {The use of social media today is not only ubiquitous and an integral part of everyday life but is also increasingly relevant before, during, or after emergencies. Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies. This chapter presents the social media API (SMA), which is a multi-platform service for gathering big social data across different social media channels and analyzing the credibility and relevance of collected data by the means of machine learning models. Based on the lessons learned from both the implementation process and user-centered evaluations in multiple emergency settings, this chapter discusses core challenges and potentials of the SMA and similar services, focusing on (1) the multi-platform gathering and management of data, (2) the mitigation of information overload by relevance assessment and message grouping, (3) the assessment of credibility and information quality, and (4) user-centered tailorability and adjustable data operations.},

abstract = {The use of Open Source Intelligence (OSINT) to monitor and detect cybersecurity threats is gaining popularity among Cybersecurity Emergency or Incident Response Teams (CERTs/CSIRTs). They increasingly use semi-automated OSINT approaches when monitoring cyber threats for public infrastructure services and incident response. Most of the systems use publicly available data, often focusing on social media due to timely data for situational assessment. As indirect and affected stakeholders, the acceptance of OSINT systems by users, as well as the conditions which influence the acceptance, are relevant for the development of OSINT systems for cybersecurity. Therefore, as part of the ethical and social technology assessment, we conducted a survey (N=1,093), in which we asked participants about their acceptance of OSINT systems, their perceived need for open source surveillance, as well as their privacy behavior and concerns. Further, we tested if the awareness of OSINT is an interactive factor that affects other factors. Our results indicate that cyber threat perception and the perceived need for OSINT are positively related to acceptance, while privacy concerns are negatively related. The awareness of OSINT, however, has only shown effects on people with higher privacy concerns. Here, particularly high OSINT awareness and limited privacy concerns were associated with higher OSINT acceptance. Lastly, we provide implications for further research and the use of OSINT systems for cybersecurity by authorities. As OSINT is a framework rather than a single technology, approaches can be selected and combined to adhere to data minimization and anonymization as well as to leverage improvements in privacy-preserving computation and machine learning innovations. Regarding the use of OSINT, the results suggest to favor approaches that provide transparency to users regarding the use of the systems and the data they gather.},

abstract = {Cryptography has become ubiquitous in communication technology and is considered a necessary part of information security. However, both the regulation to restrict access to cryptography, as well as practices to weaken or break encryption, are part of the States’ security policies. The United States (U.S.) regulate cryptography for export in international trade as a dual-use good. However, the regulation has been increasingly loosened and transferred to bilateral agreements with Information and Communication Technology companies. At the same time, the National Security Agency attempted to implement a government encryption standard to guarantee itself easier access to data, thus progressively expanding surveillance on non-U.S. citizens. In this paper, using comparative policy analysis, we examine the evolution of both security policies by tracing the historical development of U.S. regulation of cryptography as a dual-use good, and surveillance technologies, and practices used from the 1990s to today. We conclude that the impact of the dual-use regulation has affected the efficiency of surveillance technology, by loosening regulations only for mass communication services, thereby supporting the proliferation of surveillance intermediaries, while working on strategies to collaborate and exploit their coverage.},

abstract = {Despite the merits of digitization in private and professional spaces, critical infrastructures and societies are increasingly exposed to cyberattacks. We conducted a representative survey with German citizens (N=1,093) to examine how they assess the current and future cyber threat situation as well as possible protective measures in cyberspace. Furthermore, we asked what information and channels citizens need to be aware of cyber threats. Our findings indicate that large proportions of the German population feel inadequately informed about cyber threats and tend to only apply enforced security measures by programs (e.g., updates) and services (e.g., two-factor authentication). Furthermore, institutions such as state-level Computer Emergency Response Teams (CERTs) are relatively unknown among the population and respondents showed little confidence in German security authorities to cope with largescale attacks and ultimately protect citizens. Still, our participants prefer to receive cybersecurity information via installed security applications, television channels, or emergency warning apps.},

In Germany, Computer Emerrgency Response Teams (CERTs) of the public sector operate on federal and state level to provide preventative and reactive information security services for authorities, citizens, and enterprises. Their tasks of monitoring, analyzing, and communicating threats is getting more complex by the increasing information quantity disseminated into relevant public channels. Using the lens of design science research, this paper contributes with the design and evaluation of a cross-platform cybersecurity dashboard for CERTs. Based on expert scenario-based walkthroughs in combination with semi-structured interviews (N=12), it discusses six design implications, including the customizability of data sources and filtering of displayed entities, modular integration of additional information sources, interrelation between different information feeds, intelligent algorithms for content assessment and filtering, integration with security software and systems, as well as export, sharing and communication of relevant data.},

In a dynamic field like cybersecurity, gathering up-to-date information is usually a manual, time-consuming, and exhaustive task. Automatic and usable approaches are supposed to be a solution to this problem, but for this, they require a notion of information relevance to distinguish relevant from irrelevant information. First, on the basis of a literature review, this paper proposes a novel cybersecurity tool categorization based on corresponding tool types with their respective definitions and core features. Second, it elaborates information used in each category and deduces notions of relevance. Third, it outlines how these findings informed the design of a security dashboard to guide computer emergency response team staff in identifying current threats in open source intelligence sources while mitigating information overload.},

abstract = {In many cases of machine learning, research suggests that the development of training data might have a higher relevance than the choice and modelling of classifiers themselves. Thus, data augmentation methods have been developed to improve classifiers by artificially created training data. In NLP, there is the challenge of establishing universal rules for text transformations which provide new linguistic patterns. In this paper, we present and evaluate a text generation method suitable to increase the performance of classifiers for long and short texts. We achieved promising improvements when evaluating short as well as long text tasks with the enhancement by our text generation method. Especially with regard to small data analytics, additive accuracy gains of up to 15.53\% and 3.56\% are achieved within a constructed low data regime, compared to the no augmentation baseline and another data augmentation technique. As the current track of these constructed regimes is not universally applicable, we also show major improvements in several real world low data tasks (up to +4.84 F1-score). Since we are evaluating the method from many perspectives (in total 11 datasets), we also observe situations where the method might not be suitable. We discuss implications and patterns for the successful application of our approach on different types of datasets.},

abstract = {The number of newly published vulnerabilities is constantly increas-
ing. Until now, the information available when a new vulnerability
is published is manually assessed by experts using a Common Vul-
nerability Scoring System (CVSS) vector and score. This assessment
is time consuming and requires expertise. Various works already
try to predict CVSS vectors or scores using machine learning based
on the textual descriptions of the vulnerability to enable faster as-
sessment. However, for this purpose, previous works only use the
texts available in databases such as National Vulnerability Database.
With this work, the publicly available web pages referenced in the
National Vulnerability Database are analyzed and made available
as sources of texts through web scraping. A Deep Learning based
method for predicting the CVSS vector is implemented and eval-
uated. The present work provides a classification of the National
Vulnerability Database’s reference texts based on the suitability
and crawlability of their texts. While we identified the overall in-
fluence of the additional texts is negligible, we outperformed the
state-of-the-art with our Deep Learning prediction models.},

In order to respond to new threats, CERTs need to gather information in a timely and comprehensive manner. However, the volume of information and sources can lead to information overload. This paper answers the question of how to reduce information overload for CERTs with the help of clustering methods. Conditions for such a framework were established and subsequently tested. In order to perform an evaluation, different types of evaluation metrics were introduced and selected in relation to the framework conditions. Furthermore, different vectorizations and distance measures in combination with the clustering methods were evaluated and interpreted. Two different ground-truth datasets were used for the evaluation, one containing threat messages and a dataset with messages from different news categories. The work shows that the K-means clustering method along with TF-IDF vectorization and cosine distance provide the best results in the domain of threat messages.},

In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing. We find an overall positive image of the police and uncritical attitudes towards ICT used for general surveillance (body-worn cameras, video surveillance, face recognition) and slightly more critical attitudes towards personal surveillance (e.g. through communication data retention). The study indicates that perceptions differ according to experience of unfair treatment by the police, while other factors such as age and education have similar effects.},

Previous work has shown that machine readable information is either missing, incorrect, or inconsistent with other data sources. In this paper, we introduce a system called Overt Vulnerability source ANAlysis (OVANA), utilizing state-of-the-art machine learning (ML) and natural-language processing (NLP) techniques, which analyzes the information quality (IQ) of vulnerability databases, searches the free-form description for relevant information missing from structured fields, and updates it accordingly. Our paper shows that OVANA is able to improve the IQ of the National Vulnerability Database by 51.23\% based on the indicators of accuracy, completeness, and uniqueness. Moreover, we present information which should be incorporated into the structured fields to increase the uniqueness of vulnerability entries and improve the discriminability of different vulnerability entries. The identified information from OVANA enables a more targeted vulnerability search and provides guidance for IT security experts in finding relevant information in vulnerability descriptions for severity assessment.},

While information disseminated in social media can lead to valuable insights, emergency services and researchers face the challenge of information overload as data quickly exceeds the manageable amount. We propose an embedding-based clustering approach and a method for the automated labelling of clusters. Given that the clustering quality is highly dependent on embeddings, we evaluate 19 embedding models with respect to time, internal cluster quality, and language invariance. The results show that it may be sensible to use embedding models that were already trained on other crisis datasets. However, one must ensure that the training data generalizes enough, so that the clustering can adapt to new situations. Confirming this, we found out that some embeddings were not able to perform as well on a German dataset as on an English dataset.},

In several domains, such as crisis management or political communication, it is of utmost importance to detect false and to promote credible information. Although educational measures might help individuals to detect false information, the sheer volume of social big data, which sometimes need to be anal- ysed under time-critical constraints, calls for automated and (near) real- time assessment methods. Hence, this paper reviews existing approaches before designing and evaluating three deep learning models (MLP, RNN, BERT) for real-time credibility assessment using the example of Twitter posts. While our BERT implementation achieved best results with an accuracy of up to 87.07\% and an F1 score of 0.8764 when using meta- data, text, and user features, MLP and RNN showed lower classification quality but better performance for real-time application.

Thus, Computer Emergency Response Teams (CERTs) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberattacks. However, their tasks are getting more complex by the increasing amount and varying quality of information dissem-inated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYWARN project, which seeks to design strategies and technolo-gies for cross-platform cyber situational awareness and actor-spe-cific cyber threat communication. Second, it identifies and elabo-rates eight research challenges with regard to the monitoring, analysis and communication of cyber threats in CERTs, which serve as a starting point for in-depth research within the project.},

abstract = {Receiving relevant information on possible cyber threats, attacks, and data breaches in a timely manner is crucial for early response. The social media platform Twitter hosts an active cyber security community. Their activities are often monitored manually by security experts, such as Computer Emergency Response Teams (CERTs). We thus propose a Twitter-based alert generation system that issues alerts to a system operator as soon as new relevant cyber security related topics emerge. Thereby, our system allows us to monitor user accounts with significantly less workload. Our system applies a supervised classifier, based on active learning, that detects tweets containing relevant information. The results indicate that uncertainty sampling can reduce the amount of manual relevance classification effort and enhance the classifier performance substantially compared to random sampling. Our approach reduces the number of accounts and tweets that are needed for the classifier training, thus making the tool easily and rapidly adaptable to the specific context while also supporting data minimization for Open Source Intelligence (OSINT). Relevant tweets are clustered by a greedy stream clustering algorithm in order to identify significant events. The proposed system is able to work near real-time within the required 15-minutes time frame and detects up to 93.8\% of relevant events with a false alert rate of 14.81\%.},

abstract = {Smart cities aim at improving efficiency while providing safety and security by merging conventional infrastructures with information and communication technology. One strategy for mitigating hazardous situations and improving the overall resilience of the system is to involve citizens. For instance, smart grids involve prosumers - capable of producing and consuming electricity - who can adjust their electricity profile dynamically (i.e., decrease or increase electricity consumption), or use their local production to supply electricity to the grid. This mitigates the impact of peak-consumption periods on the grid and makes it easier for operators to control the grid. This involvement of prosumers is accompanied by numerous socio-technical challenges, including motivating citizens to contribute by adjusting their electricity consumption to the requirements of the energy grid. Towards this end, this work investigates motivational strategies and tools, including nudging, persuasive technologies, and incentives, that can be leveraged to increase the motivation of citizens. We discuss long-term and side effects and ethical and privacy considerations, before portraying bug bounty programs, gamification and apps as technologies and strategies to communicate the motivational strategies to citizens.},

Dementsprechend müssen die eingesetzten Systeme für einen widerstandsfähigen Betrieb ausgelegt sein. Dies gilt auch für die auf landwirtschaftlichen Betrieben eingesetzte Software, die Sicherheits- und Resilienzkriterien genügen muss. Jedoch ist die Zunahme an Software zu beobachten, welche eine permanente Internetkonnektivität erfordert, d. h. eine stabile Verbindung zu Servern oder Cloud-Applikationen ist für deren Funktionsweise erforderlich. Dies stellt eine erhebliche Schwachstelle hinsichtlich der Resilienz dar und kann bei Ausfällen der Telekommunikationsinfrastruktur zu großen Problemen führen. Mit Entwicklungen aus dem Bereich Resilient Smart Farming (RSF) zeigen wir, wie Datenhaltung nach dem Offline-First-Prinzip gestaltet werden kann. Ein zentraler Bestandteil hierbei ist das Resilient Edge Computing (REC) und die entwickelte HofBox: ein Mini-Server, der das Datenmanagement im Betrieb übernimmt und mittels innovativer Open-Source basierender Container-Technologie (Open Horizon) umsetzt.

abstract = {Farm Management Information Systems (FMIS) are an important core component of modern farming companies as they allow, e.g., to document activities, create fertilization plans, and feed digital equipment with required data. Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

abstract = {Since communications infrastructure is subject to many impacts, e.g., destructive natural events, they can potentially collapse at any time. Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

Although LoRaWAN is a frequently used representative here, there are sometimes large differences between the proposed range and the results of some practical evaluations. Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values. Nevertheless, the results certify that LoRaWAN technology has a high range that cannot be achieved with other common technologies for emergency communications.},

abstract = {The backbone network of submarine communication cables (SCC) carries 98\% of international internet traffic. Coastal and island states strongly depend on this physical internet infrastructure to provide internet connectivity. Although about 100 SCC breakdowns of human or natural origin occur at yearly average, a literature review reveals that there is no approach to assess individual state vulnerability to SCC failure in global comparison. In this article, the global SCC network is modeled based on publicly available data. Besides the analysis of the global network properties, a focus is put on remaining bandwidth capacities in three different failure scenario simulations of SCC breakdowns. As a result, this study identifies 15 highly vulnerable states and overseas territories, and another 28 territories that are classified as partially vulnerable to SCC failures. Since economic market decisions shape the structure of the SCC network, an uneven distribution of redundancies and the resulting vulnerability of disadvantaged economies can be confirmed. Therefore, the study's findings may contribute to a better assessment of the necessity of preventive protection measures of critical telecommunication infrastructures in states and territories characterized by high and medium vulnerability.},

Since data are hardly controllable once they have been published or shared with others, it is highly important that users are clearly informed about who has access to which data and how certain settings can prevent the disclosure of sensitive data. However, giving end users more control over their data through increased transparency could also lead to information overload. This is particularly true in the field of agriculture, where tight schedules put pressure on employees of small enterprises. We conduct an empirical prestudy with 52 German farmers to investigate current data sharing scenarios. From these insights, we derive requirements and a concept for data sharing solutions providing data flow transparency for users. To investigate the behavior of users and the effects of transparent UI controls, we evaluate a prototype with 18 persons. Our evaluation shows that farmers demand flexible and secure tools that adjust to their workflows. Also, data should be stored and processed locally, granting farmers data sovereignty. Although the controls require additional effort, the evaluated transparent controls for data disclosure are easy to use and raise user awareness.},

The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.},

abstract = {Mit der globalen COVID-19-Pandemie und dem Hochwasser in West- und Mitteleuropa im Sommer 2021 hat unter anderem Deutschland in jüngster Vergangenheit zwei schwerwiegende Krisenszenarien erlebt. Die Auswirkungen auf die Gesellschaft und Wirtschaft sind verheerend. Parallel lassen sich Krisenereignisse im digitalen Raum, wie die Zunahme an Cyberkriminalität beobachten. Es wird zunehmend deutlich, dass die Resilienz analoger sowie digitaler Prozesse wichtiger für die vollständige Betriebsfähigkeit wird. Die vorliegende Arbeit setzt sich mit der Bedeutung des Resilient Smart Farming (RSF) in Krisenzeiten als Möglichkeit für eine nachhaltige, umweltgerechte und resiliente digitale Landwirtschaft auseinander. Dazu wurden u.a. lokale Schadensmeldungen gruppiert und mögliche RSF-Gegenmaßnahmen aufgezeigt. Im Ergebnis zeigt sich eine Bewertung von Konzepten des RSF hinsichtlich der Krisenprävention und -bewältigung anhand aktueller realer Beispiele. Aufgrund zunehmender Bedrohungen durch Naturkatastrophen und Cyberkriminialität gehen wir davon aus, dass die Aufmerksamkeit von Gesellschaft und Politik für die Resilienz der Primärproduktion weiter steigen wird.},

Based on a precise description of the goals and applications of data augmentation and a taxonomy for existing works, this survey is concerned with data augmentation methods for textual classification and aims to provide a concise and comprehensive overview for researchers and practitioners. Derived from the taxonomy, we divide more than 100 methods into 12 different groupings and give state-of-the-art references expounding which methods are highly promising by relating them to each other. Finally, research perspectives that may constitute a building block for future work are provided.},

abstract = {The use of social media today is not only ubiquitous and an integral part of everyday life but is also increasingly relevant before, during, or after emergencies. Data produced in these contexts, such as situational updates and multimedia content, is disseminated across different social media platforms and can be leveraged by various actors, including emergency services or volunteer communities. However, the dissemination of several thousand or even millions of messages during large-scale emergencies confronts analysts with challenges of information quality and overload. Hence, crisis informatics as a research domain seeks to explore and develop systems that support the collection, analysis, and dissemination of valuable social media information in emergencies. This chapter presents the social media API (SMA), which is a multi-platform service for gathering big social data across different social media channels and analyzing the credibility and relevance of collected data by the means of machine learning models. Based on the lessons learned from both the implementation process and user-centered evaluations in multiple emergency settings, this chapter discusses core challenges and potentials of the SMA and similar services, focusing on (1) the multi-platform gathering and management of data, (2) the mitigation of information overload by relevance assessment and message grouping, (3) the assessment of credibility and information quality, and (4) user-centered tailorability and adjustable data operations.},

Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

In this paper, we analyzed these events in Germany in recent years and found out how they can be detected, and what impact they have on citizens, especially in crisis situations. For this purpose, we take a look at two different approaches to recording internet outages, namely the self-reporting of citizens and automatic reporting by algorithmic examination of the availability of IP networks. We evaluate the data of six major events with regard to their meaningfulness in quality and quantity. We found that due to the amount of data and the inherent imprecision of the methods used, it is difficult to detect outages through algorithmic examination. But once an event is publicly known by self-reporting, they have advantages to capture the temporal and spatial dimensions of the outage due to its nature of objective measurements. As a result, we propose that users’ crowdsourcing can enhance the detection of outages and should be seen as an important starting point to even begin an analysis with algorithm-based techniques, but it is to ISPs and regulatory authorities to support that.},

In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing. We find an overall positive image of the police and uncritical attitudes towards ICT used for general surveillance (body-worn cameras, video surveillance, face recognition) and slightly more critical attitudes towards personal surveillance (e.g. through communication data retention). The study indicates that perceptions differ according to experience of unfair treatment by the police, while other factors such as age and education have similar effects.},

Die Analyse ergab, dass sich Einbindung von BürgerInnen in politische Entscheidungen und bei der Entwicklung technischer Artefakte maßgeblich auf e‑Government oder Participatory Design bezieht. Im Hinblick auf die Beteiligungsarten zeigt sich, dass Makrofabriken, Living Labs und Open-Data-Plattformen häufige Ansätze sind, um BürgerInnen als Co-Creators einzubinden. Zudem werden BürgerInnen mit Citizen Sensing zur Erfassung von Daten oder Missständen einbezogen. Dabei zeigen sich sowohl aktivere, als auch eher passive Beteiligungsarten. Die Analyse zeigt, dass die Einbindung von BürgerInnen häufig entweder auf eine Beteiligung an politischen Entscheidungen oder an der Entwicklung technischer Artefakte abzielt. Auch wenn keine klare Abgrenzung möglich ist, sind diese Ansätze dann eher durch e‑Government oder Participatory Design inspiriert.},

abstract = {Smart cities aim at improving efficiency while providing safety and security by merging conventional infrastructures with information and communication technology. One strategy for mitigating hazardous situations and improving the overall resilience of the system is to involve citizens. For instance, smart grids involve prosumers - capable of producing and consuming electricity - who can adjust their electricity profile dynamically (i.e., decrease or increase electricity consumption), or use their local production to supply electricity to the grid. This mitigates the impact of peak-consumption periods on the grid and makes it easier for operators to control the grid. This involvement of prosumers is accompanied by numerous socio-technical challenges, including motivating citizens to contribute by adjusting their electricity consumption to the requirements of the energy grid. Towards this end, this work investigates motivational strategies and tools, including nudging, persuasive technologies, and incentives, that can be leveraged to increase the motivation of citizens. We discuss long-term and side effects and ethical and privacy considerations, before portraying bug bounty programs, gamification and apps as technologies and strategies to communicate the motivational strategies to citizens.},

Based on a workshop with civil protection (N=12) and police officers (N=15), we designed a questionnaire and conducted a representative survey of German citizens (N=1.219) on the past, current and future use, perceived helpfulness, deployment and behavioural preferences, configurability and most important functionality of mobile crisis apps. Our results indicate that in addition to emergency and weather warnings, crime- and health-related warnings are also desired by many, as is the possibility for bidirectional communication. People also want one central app and are resistant to installing more than one crisis app. Furthermore, there are few significant differences between socioeconomic groups.},

Under the patronage of the federal government of Germany, 28,361 participants worked together in 1,498 projects, finding innovative apps and solutions against the COVID-19 pandemic. Three months after the event, we present an exemplifying analysis of the topics, used technologies and remaining activity of these projects. Shedding light on this instance of citizen science allows to highlight the potential of hackathons and startup culture regarding socio-technological resilience. At the same time, it may be understood as an impulse for crisis informatics to consider new forms of volunteering in the course of crisis management.},

As a result, so-called “Smart Cities” have complex IT infrastructures and cyber-physical systems such as sensor/actuator networks for the general population and are developing worldwide. Urban infrastructure must be secured against attacks, ensuring reliable and resilient services for citizens as well as privacy and data security. This paper introduces selected challenges faced by infrastructure providers, citizens and decision-makers in handling attacks aimed at information and communication technologies (ICT) of urban infrastructures and presents current research avenues for tackling cyberattacks and for developing tools for creating, portraying and disseminating actiona-ble information as one important response to security challenges.

To provide empirical evidence we present a comparison of two surveys, conducted across Europe with emergency services in 2014 and 2017 respectively, with a total of 1169 answers. The analysis shows that personal experience has an effect on how organisational usage of social media is perceived and how emergency service staff view the future use of social media. Furthermore, the use has increased. This article not only shows emergency services what their staff think about their social media usage but also discusses challenges and future directions for the design of systems that can be useful for further development of optimized organisational social media usage.},

Currently appointed Information and Communications Technology (ICT) used for coordination and communication is sometimes outdated and does not scale, while novel technologies have the potential to greatly improve disaster response efficiency. To allow adoption of these novel technologies, ICT system designers have to take into account the particular needs of DROs and characteristics of International Disaster Response (IDR). This work attempts to bring the humanitarian and ICT communities closer together. In this work, we analyze IDR-related documents and conduct expert interviews. Using open coding, we extract empirical insights and translate the peculiarities of DRO coordination and operation into tangible ICT design requirements. This information is based on interviews with active IDR staff as well as DRO guidelines and reports. Ultimately, the goal of this paper is to serve as a reference for future ICT research endeavors to support and increase the efficiency of IDR operations.},

abstract = {The research field of crisis informatics examines, amongst others, the potentials and barriers of social media use during disasters and emergencies. Social media allow emergency services to receive valuable information (e.g., eyewitness reports, pictures, or videos) from social media. However, the vast amount of data generated during large-scale incidents can lead to issue of information overload. Research indicates that supervised machine learning techniques are sui- table for identifying relevant messages and filter out irrelevant messages, thus mitigating in- formation overload. Still, they require a considerable amount of labeled data, clear criteria for relevance classification, a usable interface to facilitate the labeling process and a mechanism to rapidly deploy retrained classifiers. To overcome these issues, we present (1) a system for social media monitoring, analysis and relevance classification, (2) abstract and precise criteria for re- levance classification in social media during disasters and emergencies, (3) the evaluation of a well-performing Random Forest algorithm for relevance classification incorporating metadata from social media into a batch learning approach (e.g., 91.28\%/89.19\% accuracy, 98.3\%/89.6\% precision and 80.4\%/87.5\% recall with a fast training time with feature subset selection on the European floods/BASF SE incident datasets), as well as (4) an approach and preliminary eva- luation for relevance classification including active, incremental and online learning to reduce the amount of required labeled data and to correct misclassifications of the algorithm by feed- back classification. Using the latter approach, we achieved a well-performing classifier based on the European floods dataset by only requiring a quarter of labeled data compared to the tradi- tional batch learning approach. Despite a lesser effect on the BASF SE incident dataset, still a substantial improvement could be determined.},

Basing our questionnaire on a workshop with police officers, we present the results of a representative study on citizens' perception of social media in emergencies that we conducted in Germany. Our study suggests that when it comes to emergencies, socio-demographic differences are largely insignificant and no clear preferences for emergency services' social media strategies exist. Due to the widespread searching behavior on some platforms, emergency services can reach a wide audience by turning to certain channels but should account for groups with distinct preferences.},

abstract = {Cryptography has become ubiquitous in communication technology and is considered a necessary part of information security. However, both the regulation to restrict access to cryptography, as well as practices to weaken or break encryption, are part of the States’ security policies. The United States (U.S.) regulate cryptography for export in international trade as a dual-use good. However, the regulation has been increasingly loosened and transferred to bilateral agreements with Information and Communication Technology companies. At the same time, the National Security Agency attempted to implement a government encryption standard to guarantee itself easier access to data, thus progressively expanding surveillance on non-U.S. citizens. In this paper, using comparative policy analysis, we examine the evolution of both security policies by tracing the historical development of U.S. regulation of cryptography as a dual-use good, and surveillance technologies, and practices used from the 1990s to today. We conclude that the impact of the dual-use regulation has affected the efficiency of surveillance technology, by loosening regulations only for mass communication services, thereby supporting the proliferation of surveillance intermediaries, while working on strategies to collaborate and exploit their coverage.},

abstract = {The revelation of the Stuxnet malware in 2010 shed light on the presence of state actors that are willing and capable of developing and using highly sophisticated, specialized malicious software for their political interests. These tools -often dubbed cyber weapons -are expected to become the next major advancement in weaponry technology. Besides the threats of offensive cyber operations for civil IT systems due to the interconnected nature of the cyberspace, international regulation of cyber weapons is -among other aspects -hindered by the fact that the military development and the strategic and tactical deployment of cyber weapons differ significantly from other weapons technologies. In order to establish measures of cyber arms related control treaties, it is crucial to identify these particular characteristics. Based on this premise, the article analyzes the current perspectives on cyber weapons, identifying their weaknesses of being either based on assumptions about adversarial actors or being applicable only after the usage of a malicious tool. In contrast to these approaches, the article focuses on the specific functional aspects of malware and presents an indicator-based assessment model based on parameters that can be measured prior to the application of malicious software. This enables the categorization of malicious tools as cyber weapons. Besides this, the article aims to introduce thought-provoking impulses with regard to social responsibility in computer science.},

abstract = {Looking at a variety of armament sectors, the book examines how Artificial Intelligence (AI) impacts the fields of armament and arms control, how existing arms control measures will be affected by AI, and what new approaches based on AI have been or are currently developed.
The significant increase in computing power, the increasing reliance on software, and the advent of (narrow) AI and deep-learning algorithms all have the potential to lead to disruptive changes for military operations and warfare, rendering many classical arms control instruments less effective, or even useless. On the other hand, AI might lead to completely new arms control approaches, raising the effectiveness and reliability of new verification measures. To provide a common understanding, the book starts by presenting a general introduction to the state of the art in artificial intelligence and arms control, and how the two topics are interrelated. The second part of the book looks at examples from various fields of weapon technology, including weapons of mass destruction (WMD), conventional armament, and emerging technologies. The final section offers a cross-cutting perspective based on the examples presented in the second part.
This volume will appeal to students and scholars of international relations, as well as policy-makers and practitioners interested in a better understanding of peace and security studies in general, and armament and arms control in particular with a strong focus on AI.},

Warning about control failures and accidental war on one hand, Din also pointed out the potential of AI to enhance arms control. 35 years later, what was a niche technology in Din’s day has since become one of the most influential technologies in both the civilian and military sectors. In addition, AI has evolved from sophisticated yet deterministic expert systems to machine learning algorithms. Today, AI is about to be introduced in almost every branch of the military, with a variety of implications for arms control. This book reflects the work of the individual authors and identifies common themes and areas where AI can be used for the greater good or where its use calls for particular vigilance. It offers an essential primer for interested readers, while also encouraging experts from the arms control community to dig more deeply into the issues.},

abstract = {Warning and emergency apps are an integral part of crisis informatics and particularly relevant in countries that currently do not have cell broadcast, such as Germany. Previous studies have shown that such apps are regarded as relevant, but only around 16\% of German citizens used them in 2017 and 2019. With the COVID-19 pandemic and a devastating flash flood, Germany has recently experienced severe crisis-related losses. By comparing data from representative surveys from 2017, 2019 and 2021, this study investigates whether these events have changed the perceptions of warning apps and their usage patterns in Germany. The study shows that while multi-hazard emergency and warning apps have been easily surpassed in usage by COVID-19 contact tracing apps, the use of warning apps has also increased and the pandemic has added new desired features. While these have been little-used during the COVID-19 pandemic, especially non-users see smartphone messengers app channels as possible alternatives to warning apps. In addition, regional warning apps appear promising, possibly because they make choosing a warning app easier when there are several available on the market.},

Recent research has highlighted, on the one hand, the use of social media as a means of recruitment by terrorists and, on the other hand, the use of Facebook, Twitter etc. to gain the support of the population during insurgencies. This article conducts a qualitative content analysis of content on Twitter concerning the conflict in the Jammu and Kashmir region. The tweets following the death of a popular militant, Burhan Wani, cover three different themes: (1) criticism of intellectuals, (2) Burhan Wani's impact on the conflict, and (3) tweets referring to the conflict itself. Generally, people use Twitter to make their own point of view clear to others and discredit the opposing party, at the same time tweets are reflecting the antagonism between the two parties to the conflict, India and Pakistan. The sample of tweets reflects the lack of awareness among people in the region regarding the motivations of the new generation of militancy emerging in Kashmir after 1990.},

In order to respond to new threats, CERTs need to gather information in a timely and comprehensive manner. However, the volume of information and sources can lead to information overload. This paper answers the question of how to reduce information overload for CERTs with the help of clustering methods. Conditions for such a framework were established and subsequently tested. In order to perform an evaluation, different types of evaluation metrics were introduced and selected in relation to the framework conditions. Furthermore, different vectorizations and distance measures in combination with the clustering methods were evaluated and interpreted. Two different ground-truth datasets were used for the evaluation, one containing threat messages and a dataset with messages from different news categories. The work shows that the K-means clustering method along with TF-IDF vectorization and cosine distance provide the best results in the domain of threat messages.},

ing. Until now, the information available when a new vulnerability
is published is manually assessed by experts using a Common Vul-

try to predict CVSS vectors or scores using machine learning based
on the textual descriptions of the vulnerability to enable faster as-
sessment. However, for this purpose, previous works only use the
texts available in databases such as National Vulnerability Database.
With this work, the publicly available web pages referenced in the
National Vulnerability Database are analyzed and made available
as sources of texts through web scraping. A Deep Learning based
method for predicting the CVSS vector is implemented and eval-
uated. The present work provides a classification of the National
Vulnerability Database’s reference texts based on the suitability
and crawlability of their texts. While we identified the overall in-
fluence of the additional texts is negligible, we outperformed the
state-of-the-art with our Deep Learning prediction models.},

The work empirically shows that social media is increasingly important for emergency services, both for prevention and during crises; that private use of social media is a driving force in shaping opinions for organisational use; and that citizens have high expectations towards authorities, especially monitoring social media is expected, and sometimes responses within one hour. Depending on the risk culture, the data show further differences, e.g. whether the state (Germany) or the individual (Netherlands) is seen as primarily responsible for coping with the situation.},

abstract = {Mobile technologies and social media services are among the socio-technological innovations that have an enormous impact transforming modern culture and political processes. Social media are often defined as a “group of internet-based applications […] that allow the creation and exchange of user-generated content” (Kaplan and Haenlein 2010). Shaping opinions, politics, participation, and protest (Wulf et al. 2013), they are used by citizens for news consumption and social exchange (Robinson et al. 2017); by journalists for reporting, analyzing, and collecting information (Stieglitz et al. 2018a); and by organizations to monitor crises, emergencies, customer feedback, and sentiment, among others (Haunschild et al. 2020). Large-scale international events, such as the 2010 Arab Spring, showcased the potential of socio-technological transformations: Citizens were not passive victims but active and autonomous participants utilizing social media to coordinate protest and for crisis response (Reuter and Kaufhold 2018). However, in other cases, citizens’ activities coordinated via social media also increased the complexity of tasks and pressure for formal authorities, since the lack of state control has not had only empowering or benign effects. Instead, on social media, false information spreads fast and it is easy for groups to find an audience there, either to enhance their profit or to target vulnerable groups with dangerous ideology.},

In a dynamic field like cybersecurity, gathering up-to-date information is usually a manual, time-consuming, and exhaustive task. Automatic and usable approaches are supposed to be a solution to this problem, but for this, they require a notion of information relevance to distinguish relevant from irrelevant information. First, on the basis of a literature review, this paper proposes a novel cybersecurity tool categorization based on corresponding tool types with their respective definitions and core features. Second, it elaborates information used in each category and deduces notions of relevance. Third, it outlines how these findings informed the design of a security dashboard to guide computer emergency response team staff in identifying current threats in open source intelligence sources while mitigating information overload.},

Furthermore, we asked what information and channels citizens need to be aware of cyber threats. Our findings indicate that large proportions of the German population feel inadequately informed about cyber threats and tend to only apply enforced security measures by programs (e.g., updates) and services (e.g., two-factor authentication). Furthermore, institutions such as state-level Computer Emergency Response Teams (CERTs) are relatively unknown among the population and respondents showed little confidence in German security authorities to cope with largescale attacks and ultimately protect citizens. Still, our participants prefer to receive cybersecurity information via installed security applications, television channels, or emergency warning apps.},

The diffusion of AI from the civilian sector to the defense sector, and AI’s dual-use potential has drawn attention from security and ethics scholars. With the publication of the ethical guideline Trustworthy AI by the European Union (EU), normative questions on the application of AI have been further evaluated. In order to draw conclusions on Trustworthy AI as a point of reference for responsible research and development (R\&D), we approach the diffusion of AI across both civilian and military spheres in the EU. We capture the extent of technological diffusion and derive European and German patent citation networks. Both networks indicate a low degree of diffusion of AI between civilian and defense sectors. A qualitative investigation of project descriptions of a research institute’s work in both civilian and military fields shows that military AI applications stress accuracy or robustness, while civilian AI reflects a focus on human-centric values. Our work represents a first approach by linking processes of technology diffusion with normative evaluations of R\&D.},

abstract = {The European Union (EU) has undertaken policies which address the research and development of artificial intelligence (AI). In light of debates of technology assessment which focus on risks for humans and questions of control of AI, the EU has propagated an ethical, human-centred approach of the application of AI. It is important to identify how the EU envisions AI as this may guide emerging norms in AI governance and today’s research and development of (weaponised) AI. Building on works of Human-Computer Interaction (HCI), this work derives the actor’s understanding of human-AI interaction, including conceptualisations of explainability, interpretability, and risks. Analysis of EU documents on the implementation of AI as a general-purpose technology and for military application reveals that explainability and risk identification are crucial elements for trust, which itself is a necessary component in the uptake of AI. Interdisciplinary approaches allow for a more detailed understanding of actors’ fundamental views on human control of AI, which further contributes to debates on technology assessment in professionalised political contexts.},

abstract = {The backbone network of submarine communication cables (SCC) carries 98\% of international internet traffic. Coastal and island states strongly depend on this physical internet infrastructure to provide internet connectivity. Although about 100 SCC breakdowns of human or natural origin occur at yearly average, a literature review reveals that there is no approach to assess individual state vulnerability to SCC failure in global comparison. In this article, the global SCC network is modeled based on publicly available data. Besides the analysis of the global network properties, a focus is put on remaining bandwidth capacities in three different failure scenario simulations of SCC breakdowns. As a result, this study identifies 15 highly vulnerable states and overseas territories, and another 28 territories that are classified as partially vulnerable to SCC failures. Since economic market decisions shape the structure of the SCC network, an uneven distribution of redundancies and the resulting vulnerability of disadvantaged economies can be confirmed. Therefore, the study's findings may contribute to a better assessment of the necessity of preventive protection measures of critical telecommunication infrastructures in states and territories characterized by high and medium vulnerability.},

So existieren bereits viele Smart-City-Initiativen, bei denen Städte versuchen, ihre Prozesse durch Erfassung und Verknüpfung von Daten, oft unter Zuhilfenahme von Datenplattformen, zu optimieren. In Anbetracht der damit einhergehenden großen Investitionen und Veränderungen wird Bürgerbeteiligung als zentraler Faktor für den Erfolg solcher Initiativen betrachtet. Bisher ist allerdings nicht klar, was typische Beteiligungsformate von Smart-City-Initiativen sind und welche Rolle(n) BürgerInnen dabei einnehmen. Dieser Beitrag leitet mittels einer Literaturanalyse zu Smart Cities ein Kategorienschema zu typischen Bürgerbeteiligungsarten ab. Die Analyse ergab, dass sich Einbindung von BürgerInnen in politische Entscheidungen und bei der Entwicklung technischer Artefakte maßgeblich auf e‑Government oder Participatory Design bezieht. Im Hinblick auf die Beteiligungsarten zeigt sich, dass Makrofabriken, Living Labs und Open-Data-Plattformen häufige Ansätze sind, um BürgerInnen als Co-Creators einzubinden. Zudem werden BürgerInnen mit Citizen Sensing zur Erfassung von Daten oder Missständen einbezogen. Dabei zeigen sich sowohl aktivere, als auch eher passive Beteiligungsarten. Die Analyse zeigt, dass die Einbindung von BürgerInnen häufig entweder auf eine Beteiligung an politischen Entscheidungen oder an der Entwicklung technischer Artefakte abzielt. Auch wenn keine klare Abgrenzung möglich ist, sind diese Ansätze dann eher durch e‑Government oder Participatory Design inspiriert.},

For instance, existing research suggests nudges for stronger passwords or safe WiFi connections. However, those nudges are often not as effective as desired. To improve their effectiveness, it is crucial to understand how people assess nudges in cybersecurity, to address potential fears and resulting reactance and to facilitate voluntary compliance. In other contexts, such as the health sector, studies have already thoroughly explored the attitude towards nudging. To address that matter in cybersecurity, we conducted a representative study in Germany (𝑁 = 1, 012), asking people about their attitude towards nudging in that specific context. Our findings reveal that 64\% rated nudging in cybersecurity as helpful, however several participants expected risks such as intentional misguidance, manipulation and data exposure as well.},

abstract = {Receiving relevant information on possible cyber threats, attacks, and data breaches in a timely manner is crucial for early response. The social media platform Twitter hosts an active cyber security community. Their activities are often monitored manually by security experts, such as Computer Emergency Response Teams (CERTs). We thus propose a Twitter-based alert generation system that issues alerts to a system operator as soon as new relevant cyber security related topics emerge. Thereby, our system allows us to monitor user accounts with significantly less workload. Our system applies a supervised classifier, based on active learning, that detects tweets containing relevant information. The results indicate that uncertainty sampling can reduce the amount of manual relevance classification effort and enhance the classifier performance substantially compared to random sampling. Our approach reduces the number of accounts and tweets that are needed for the classifier training, thus making the tool easily and rapidly adaptable to the specific context while also supporting data minimization for Open Source Intelligence (OSINT). Relevant tweets are clustered by a greedy stream clustering algorithm in order to identify significant events. The proposed system is able to work near real-time within the required 15-minutes time frame and detects up to 93.8\% of relevant events with a false alert rate of 14.81\%.},

abstract = {Besides the merits of increasing digitization and interconnectedness in private and professional spaces, critical infrastructures and societies are more and more exposed to cyberattacks. In order to enhance the preventative and reactive capabilities against cyberattacks, Computer Emergency Response Teams (CERTs) are deployed in many countries and organizations. In Germany, CERTs in the public sector operate on federal and state level to provide information security services for authorities, citizens, and enterprises. Their tasks of monitoring, analyzing, and communicating threats and incidents is getting more complex due to the increasing amount of information disseminated into public channels. By adopting the perspectives of Computer-Supported Cooperative Work (CSCW) and Crisis Informatics, we contribute to the study of organizational structures, technology use, and the impact on collaborative practices in and between state CERTs with empirical research based on expert interviews with representatives of German state CERTs (N=15) and supplementary document analyses (N=25). We derive design and policy implications from our findings, including the need for interoperable and modular architecture, a shift towards service level agreements, cross-platform monitoring and analysis of incident data, use of deduplication techniques and standardized threat exchange formats, a reduction of resource costs through process automation, and transparent reporting and tool structures for information exchange.},

In several domains, such as crisis management or political communication, it is of utmost importance to detect false and to promote credible information. Although educational measures might help individuals to detect false information, the sheer volume of social big data, which sometimes need to be anal- ysed under time-critical constraints, calls for automated and (near) real- time assessment methods. Hence, this paper reviews existing approaches before designing and evaluating three deep learning models (MLP, RNN, BERT) for real-time credibility assessment using the example of Twitter posts. While our BERT implementation achieved best results with an accuracy of up to 87.07\% and an F1 score of 0.8764 when using meta- data, text, and user features, MLP and RNN showed lower classification quality but better performance for real-time application. Furthermore, the paper contributes with a novel dataset for credibility assessment.},

In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing. We find an overall positive image of the police and uncritical attitudes towards ICT used for general surveillance (body-worn cameras, video surveillance, face recognition) and slightly more critical attitudes towards personal surveillance (e.g. through communication data retention). The study indicates that perceptions differ according to experience of unfair treatment by the police, while other factors such as age and education have similar effects.},

Given that the clustering quality is highly dependent on embeddings, we evaluate 19 embedding models with respect to time, internal cluster quality, and language invariance. The results show that it may be sensible to use embedding models that were already trained on other crisis datasets. However, one must ensure that the training data generalizes enough, so that the clustering can adapt to new situations. Confirming this, we found out that some embeddings were not able to perform as well on a German dataset as on an English dataset.},

Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

Our paper shows that OVANA is able to improve the IQ of the National Vulnerability Database by 51.23\% based on the indicators of accuracy, completeness, and uniqueness. Moreover, we present information which should be incorporated into the structured fields to increase the uniqueness of vulnerability entries and improve the discriminability of different vulnerability entries. The identified information from OVANA enables a more targeted vulnerability search and provides guidance for IT security experts in finding relevant information in vulnerability descriptions for severity assessment.},

abstract = {Smart cities aim at improving efficiency while providing safety and security by merging conventional infrastructures with information and communication technology. One strategy for mitigating hazardous situations and improving the overall resilience of the system is to involve citizens. For instance, smart grids involve prosumers - capable of producing and consuming electricity - who can adjust their electricity profile dynamically (i.e., decrease or increase electricity consumption), or use their local production to supply electricity to the grid. This mitigates the impact of peak-consumption periods on the grid and makes it easier for operators to control the grid. This involvement of prosumers is accompanied by numerous socio-technical challenges, including motivating citizens to contribute by adjusting their electricity consumption to the requirements of the energy grid. Towards this end, this work investigates motivational strategies and tools, including nudging, persuasive technologies, and incentives, that can be leveraged to increase the motivation of citizens. We discuss long-term and side effects and ethical and privacy considerations, before portraying bug bounty programs, gamification and apps as technologies and strategies to communicate the motivational strategies to citizens.},

Based on a workshop with civil protection (N=12) and police officers (N=15), we designed a questionnaire and conducted a representative survey of German citizens (N=1.219) on the past, current and future use, perceived helpfulness, deployment and behavioural preferences, configurability and most important functionality of mobile crisis apps. Our results indicate that in addition to emergency and weather warnings, crime- and health-related warnings are also desired by many, as is the possibility for bidirectional communication. People also want one central app and are resistant to installing more than one crisis app. Furthermore, there are few significant differences between socioeconomic groups.},

This paper introduces selected challenges faced by infrastructure providers, citizens and decision-makers in handling attacks aimed at information and communication technologies (ICT) of urban infrastructures and presents current research avenues for tackling cyberattacks and for developing tools for creating, portraying and disseminating actiona-ble information as one important response to security challenges. It then presents findings from a representative survey conducted in Germany (N=1091) on the experiences and perceptions of citizens concerning the relevance of cyberat-tacks will be presented.},

abstract = {Threats in cyberspace have increased in recent years due to the increment of offensive capabilities by states. Approaches to mitigate the security dilemma in cyberspace within the UN are deadlocked, as states have not been able to achieve agreements. However, from the perspective of IT-Security, there are Cyber Threat Intelligence (CTI) platforms to share and analyze cyber threats for a collective crisis management. To investigate, whether or not CTI platforms can be used as a confidence-building measure between states and international organizations, we portray current CTI platforms, showcase political requirements, and answer the question of how CTI communication may contribute to confidence-building in international affairs. Our results suggest the need to further develop analytical capabilities, as well as the implementation of a broad social, political, and legal environment for international CTI sharing.},

abstract = {The research field of crisis informatics examines, amongst others, the potentials and barriers of social media use during disasters and emergencies. Social media allow emergency services to receive valuable information (e.g., eyewitness reports, pictures, or videos) from social media. However, the vast amount of data generated during large-scale incidents can lead to issue of information overload. Research indicates that supervised machine learning techniques are sui- table for identifying relevant messages and filter out irrelevant messages, thus mitigating in- formation overload. Still, they require a considerable amount of labeled data, clear criteria for relevance classification, a usable interface to facilitate the labeling process and a mechanism to rapidly deploy retrained classifiers. To overcome these issues, we present (1) a system for social media monitoring, analysis and relevance classification, (2) abstract and precise criteria for re- levance classification in social media during disasters and emergencies, (3) the evaluation of a well-performing Random Forest algorithm for relevance classification incorporating metadata from social media into a batch learning approach (e.g., 91.28\%/89.19\% accuracy, 98.3\%/89.6\% precision and 80.4\%/87.5\% recall with a fast training time with feature subset selection on the European floods/BASF SE incident datasets), as well as (4) an approach and preliminary eva- luation for relevance classification including active, incremental and online learning to reduce the amount of required labeled data and to correct misclassifications of the algorithm by feed- back classification. Using the latter approach, we achieved a well-performing classifier based on the European floods dataset by only requiring a quarter of labeled data compared to the tradi- tional batch learning approach. Despite a lesser effect on the BASF SE incident dataset, still a substantial improvement could be determined.},

Basing our questionnaire on a workshop with police officers, we present the results of a representative study on citizens' perception of social media in emergencies that we conducted in Germany. Our study suggests that when it comes to emergencies, socio-demographic differences are largely insignificant and no clear preferences for emergency services' social media strategies exist. Due to the widespread searching behavior on some platforms, emergency services can reach a wide audience by turning to certain channels but should account for groups with distinct preferences.},

In addition to the concrete threat analysis, the paper identifies some general technical solutions (e.g., encryption methods, communication software) for different research steps to foster secure and ethically justifiable research.},

abstract = {The use of Open Source Intelligence (OSINT) to monitor and detect cybersecurity threats is gaining popularity among Cybersecurity Emergency or Incident Response Teams (CERTs/CSIRTs). They increasingly use semi-automated OSINT approaches when monitoring cyber threats for public infrastructure services and incident response. Most of the systems use publicly available data, often focusing on social media due to timely data for situational assessment. As indirect and affected stakeholders, the acceptance of OSINT systems by users, as well as the conditions which influence the acceptance, are relevant for the development of OSINT systems for cybersecurity. Therefore, as part of the ethical and social technology assessment, we conducted a survey (N=1,093), in which we asked participants about their acceptance of OSINT systems, their perceived need for open source surveillance, as well as their privacy behavior and concerns. Further, we tested if the awareness of OSINT is an interactive factor that affects other factors. Our results indicate that cyber threat perception and the perceived need for OSINT are positively related to acceptance, while privacy concerns are negatively related. The awareness of OSINT, however, has only shown effects on people with higher privacy concerns. Here, particularly high OSINT awareness and limited privacy concerns were associated with higher OSINT acceptance. Lastly, we provide implications for further research and the use of OSINT systems for cybersecurity by authorities. As OSINT is a framework rather than a single technology, approaches can be selected and combined to adhere to data minimization and anonymization as well as to leverage improvements in privacy-preserving computation and machine learning innovations. Regarding the use of OSINT, the results suggest to favor approaches that provide transparency to users regarding the use of the systems and the data they gather.},

abstract = {In the digital age, the vision of autonomous vehicles (AVs) is vibrant. Research is being conducted worldwide to inte-grate AVs into our everyday lives in the future, spending consid-erable amounts of money in the development process. Actors from both engineering as well as social sciences are involved in this re-search, with technical disciplines strongly dominating. In addition to perceived progress of numerous newly developed technologies such as AVs, challenges should also be referred to. According to research analysis, the transferability of autonomous cars to the military sphere seems to be frequently forgotten or ignored (dual-use). Since not much research has been conducted in Germany on the potential deployment of autonomous driving development steps into military domains, 25 semi-structured interviews with de-velopers and researchers and actors involved in the field, were conducted in 2020. The paper identifies that the majority of re-spondents interviewed were aware of general existing dual-use de-bates, however, few had reflected about dual-use issues regarding a possible transfer of their own development processes in the con-text of autonomous driving to military applications, intensively. One reason is the small-scale nature of research, another is the complexity of the field, which enables the engineer’s alienation from their responsibility for the artefacts’ use. Moreover, it has become clear that hardly any conversations among colleagues oc-cur about possible misuse and that no standardized policy guide-lines exist, which provide information about possible risk. To raise dual-use awareness, scientific contributions, risk education, and interdisciplinary discussions are essential.},

One goal of digital research is to also capture marginal-ized voices. With emerging risks related to digital research, such as digital surveillance and social media monitoring by adversaries (e.g., the military in Myanmar), research needs to be more thoughtfully conducted. Considering research ethics, an evolving discrepancy between security measures and values of social jus-tice, such as accessibility and representation, appears as most data-secure applications are not used widely and offers such as “Free Basics” entice people to use rather data-unsecure applica-tions. Reflecting on this existing discrepancy in ethical require-ments, I illustrate challenges of the German research context re-lated to digitally conducted research focusing on overt conflictive social contexts.},

Consequently, we aimed to identify them on a privacy knowledge–privacy behavior ratio based on a self-developed instrument. To achieve this, we conducted an item analysis (N = 820) and a confirmatory factor analysis (CFA) (N = 656) of data based on an online study with German participants. Starting with 81 items, we reduced those to an eleven-item questionnaire with the two scales privacy knowledge and privacy behavior. A subsequent cluster analysis (N = 656) revealed three distinct user groups: (1) Fundamentalists scoring high in privacy knowledge and behavior, (2) Pragmatists scoring average in privacy knowledge and behavior and (3) Unconcerned scoring low in privacy knowledge and behavior. In a closer inspection of the questionnaire, the CFAs supported the model with a close global fit based on RMSEA in a training and to a lesser extent in a cross-validation sample. Deficient local fit as well as validity and reliability coefficients well below generally accepted thresholds, however, revealed that the questionnaire in its current form cannot be considered a suitable measurement instrument for determining privacy personas. The results are discussed in terms of related persona conceptualizations, the importance of a methodologically sound investigation of corresponding privacy dimensions and our lessons learned.},

abstract = {Since 2015, an increased number of asylum seekers is coming to Europe. These migration movements increasingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach their targeted destination countries. Asylum seekers often use smartphones for information and communication purposes. Even though there are many positive aspects in the use of such technologies, researchers have to consider the perceived risks of this specific user group. This work aims at investigating the use of mobile information technologies by asylum seekers during their flight, especially taking privacy into account. Thus, it examines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conducting a qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results show that asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, such as surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this, this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy and trust leads to avoidance behavior, the insights of this study provide valuable information for the design of assistance apps and collaboration platforms, which appropriately address the specific needs for digital privacy in the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

Exploratory results of a survey of German private users (N=1,219) show that privacy and security behavior are only weakly correlated and not similarly influenced by socio-demographic factors. While se-curity behavior significantly differs between age and education groups (younger and less educated show less security behavior), no such differences exist for pri-vacy behavior. Additionally, political orientation and opinion has no influence on privacy and security behavior. Thus, this study sheds light on the concepts of privacy, security and corresponding behavior and emphasizes the need for a fine-grained differentiation if either privacy or security behavior is to be improved.},

Based on a workshop with civil protection (N=12) and police officers (N=15), we designed a questionnaire and conducted a representative survey of German citizens (N=1.219) on the past, current and future use, perceived helpfulness, deployment and behavioural preferences, configurability and most important functionality of mobile crisis apps. Our results indicate that in addition to emergency and weather warnings, crime- and health-related warnings are also desired by many, as is the possibility for bidirectional communication. People also want one central app and are resistant to installing more than one crisis app. Furthermore, there are few significant differences between socioeconomic groups.},

abstract = {The German Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik) offers advice and recommendations for private users on how to behave securely. Based on these recommendations we investigate the IT security knowledge and behavior of private users with a rep- resentative study of the German population (N = 1.219). Additionally, we ana- lyze the role of socio-demographic factors (gender, age, education, political ori- entation) for security knowledge and behavior. Results show that German pri- vate users have only moderate IT security knowledge and behavior, with as- pects as gender, age, education and political orientation partly having an influ- ence. Men, higher educated and politically moderately oriented participants show higher security knowledge, whereas young people and those less knowl- edgeable about security behave less security-conscious. Additionally, security knowledge and behavior correlate moderately. Therefore, to increase private users' IT security we suggest to increase education and training especially for users being young, politically right-wing or female.},

The paper raises the question if collecting people's data, and thus enabling smart cities, is ethical and if not, how it can be assured to be ethical.},

Apps used in these contexts store sensitive and valuable data, creating a need for security measures. It has not yet been researched to what extent certain authentication mechanisms, which can be information-, biometric- as well as token-based, are suitable for individual apps and the respective data. The goal of this work is to assess how perceived security and estimated effort of using such mechanisms, as well as the degree to which app data is considered worth protecting, influence users' choices of appropriate measures to protect app categories. Therefore, we conducted a representative study (n=1024). On the one hand, our results show that a positive correlation between perceived security and effort exists for all investigated non-biometric authentication methods. On the other hand, the study sheds light on the differences between the investigated app categories and the users' choice of the appropriate security mechanisms for the particular category. In contrast to perceived security having a positive influence on a user's preference of mechanism, a relation can hardly be identified for effort. Moreover, app data sensitivity does not seem relevant for the users' choice of security mechanism.},

Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people's views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63\% and 67\%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27\%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.},

Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values.

This technology could transform the sector, improving the management and quality of agricultural operations, for example, crop farming. The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.},

In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture. The result is a low robustness capacity, as our analysis concludes with the risk of food production losses.},

and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

Mit dem Einsatz moderner digitaler Werkzeuge werden Erwartungen verbunden, sowohl den gesellschaftlichen Anforderungen nach Qualität und Quantität von Nahrungsmitteln gerecht zu werden, als auch dabei die Produktion möglichst effi-zient unter Berücksichtigung von Umwelt und Natur durchzufüh-ren. Ebenso gilt es die Interessen der landwirtschaftlich Beschäftig-ten zu wahren. Die Geobox-Infrastruktur verfolgt dieses Ziel.

So-called Smart Farming uses drones and a variety of sensors to measure climate, irrigation, soil moisture or GPS position. With this rapid influx of technology increases the threat that vulnerabilities in those technologies are being exploited for malicious intent. To show the impact of cyberattacks on agriculture, we present a simulation of several attacks on a ZigBee-based wireless sensor network. We conduct a delay attack, an interference attack and three different routing attacks (sinkhole, blackhole and selective forwarding attack). Those attacks are simulated using NETA with the OMNET++ framework. We will show that the security of WSN is influenced by factors like energy consumption or computation power, which can conflict with other interests like low per-unit costs.},

One possibility to manage data and use them to create value is the blockchain-technology. It is primary enforced by the food industries and consumers to ensure traceability and transparency. To put blockchain-technology into beneficial use in agriculture, this domain has to be analyzed regarding social and business aspects. This paper presents the results of a qualitative study where 41 actors from the agricultural do-main participated in focus groups and delivered a written statement. It was found that farmers are interested in adapting new markets and technologies early to get an economic advantage. On the other hand, the fear of losing traditional local business partners and the social surroundings of the farmers must be considered},

The diffusion of AI from the civilian sector to the defense sector, and AI’s dual-use potential has drawn attention from security and ethics scholars. With the publication of the ethical guideline Trustworthy AI by the European Union (EU), normative questions on the application of AI have been further evaluated. In order to draw conclusions on Trustworthy AI as a point of reference for responsible research and development (R\&D), we approach the diffusion of AI across both civilian and military spheres in the EU. We capture the extent of technological diffusion and derive European and German patent citation networks. Both networks indicate a low degree of diffusion of AI between civilian and defense sectors. A qualitative investigation of project descriptions of a research institute’s work in both civilian and military fields shows that military AI applications stress accuracy or robustness, while civilian AI reflects a focus on human-centric values. Our work represents a first approach by linking processes of technology diffusion with normative evaluations of R\&D.},

One prominent approach for measuring spillover effects is based on the analysis of patent citation networks. Taking social media analytics and knowledge economics into account, this paper presents a complementary approach to quantify spillover effects from defense to civilian research and development, analyzing 513 employment biographies from the social network LinkedIn. Using descriptive network analysis, we investigate the emigration of personnel of the German defense industry to other civilian producers. Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

abstract = {The debate on the development and deployment of lethal autonomous weapon systems (LAWS) as an emerging technology is of increasing importance, with discussions stalling and technological development progressing. Monitoring the progress of increasingly autonomous weapons systems in civilian and military use as well as regulating possible autonomous systems early on is demanded by civil society actors, like the Campaign to Stop Killer Robots and the International Committee of the Red Cross (ICRC), while nation states follow a variety of interests and strategies, showing little room for consensus on central terms and questions [2], [3]. This article therefore sheds light on the work of the Group of Governmental Experts (GGE) of the UN Convention of Certain Conventional Weapons (CCW). The CCW, offering an arena for international cooperation, has dedicated itself to the purpose of finding common ground with respect to an understanding of LAWS, as well as to the necessary degree of human control. From an ethical perspective, the concept of Meaningful Human Control (MHC) supports a human-centric approach. Several IEEE projects, series and publications are dedicated to this prioritization, especially regarding civilian use. As autonomous technology is increasingly at the center of contemporary military innovations, questions of (human) agency and responsibility in warfare have become even more pressing. As stressed by the United Nations Institute for Disarmament Research (UNIDIR), the concept of MHC may prove useful in the context of development and use of (semi-) autonomous weaponry.},

Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people's views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63\% and 67\%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27\%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.},

Dual-use questions have been addressed in various disciplines, in particular in nuclear technology and the production of nuclear weapons, but also in chemistry and biology. In all these disciplines, dual-use topics in technical development and education have been discussed and addressed. Nevertheless, the importance of dual-use differs slightly, depending on the technology and its risks, as well as its distribution and application.

Jedoch ist die Zunahme an Software zu beobachten, welche eine permanente Internetkonnektivität erfordert, d. h. eine stabile Verbindung zu Servern oder Cloud-Applikationen ist für deren Funktionsweise erforderlich.

Since the entire agricultural sector is an essential component of food production, high standards of resilience should be established in the involved companies. Accordingly, the used software should also be designed with high standards on reliability and crisis capability. Based on a literature review, we found that software for farmers with certain resilience needs is lacking. Thus, we designed and evaluated a new FMIS concept with the user-centered design method. By conducting focus groups (two rounds, total N=57) in 2017 and 2019, we raised specific front-end and back-end requirements of farmers. Based on the requirements, we developed our concept for both front- and back-end in terms of a decentralized and offline-working FMIS. Through the evaluation with practitioners (N=16) of the implemented concept, we derived findings and implications, highlighting the need for privacy, stability, and offline-capability, as well as the UI-requirement to be supportive, e.g., with easy to understand icons and terms.},

Especially in rural areas, the recovery of public network infrastructure can take some time, so a dedicated communication channel would be advantageous. We explore the possibility of transforming commodity LoRaWAN gateways into meshed network nodes for a digital emergency communication channel. In order to obtain the required parameters, we collected farm locations in Germany with OpenStreetMap. Based on the assumptions of LoRa communication range and considering our use case requirements, connecting farm communities seems theoretically feasible in many areas of our data set. To further analyze our idea, we ran simulations of two common DTN routing protocols with different scenarios. A proof-of-concept implementation allows smaller messages to be transmitted using real hardware and demonstrates that a decentralized communications infrastructure based on commodity hardware is possible.},

Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values.

This technology could transform the sector, improving the management and quality of agricultural operations, for example, crop farming. The most promising data transmission standard for this domain seems to be Long Range Wide Area Network (LoRaWAN), a popular representative of low power wide area network technologies today. LoRaWAN, like any wireless protocol, has properties that can be exploited by attackers, which has been a topic of multiple research papers in recent years. By conducting a systematic literature review, we build a recent list of attacks, as well as collect mitigation options. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluate the practicality of both exploiting the vulnerabilities and implementing the countermeasures. We detected 16 attacks that we grouped into six attack types. Along with the attacks, we collect countermeasures for attack mitigation. Developers can use our findings to minimize the risks when developing applications based on LoRaWAN. These mostly theoretical security recommendations should encourage future works to evaluate the mitigations in practice.},

abstract = {Agriculture is subject to high demands regarding resilience as it is an essential component of the food production chain. In the agricultural sector, there is an increasing usage of digital tools that rely on communication and energy infrastructures. Should disruption occur, such strengthened dependencies on other infrastructures increase the probability of ripple effects. Thus, there is a need to analyze the resilience of the agricultural sector with a specific focus on the effects of digitalization. This study works out resilience capacities of the interconnected technologies used in farm systems based on the experiences and opinions of farmers. Information was gathered through focus group interviews with farmers (N = 52) and a survey with participants from the agricultural sector (N = 118). In particular, the focus is put on the digital tools and other information and communication technologies they use. Based on a definition of resilience capacities, we evaluate resilience regarding energy and communication demands in various types of farm systems. Especially important are the resilience aspects of modern systems’ digital communication as well as the poorly developed and nonresilient network infrastructure in rural areas that contrast with the claim for a resilient agriculture.

abstract = {Mit der globalen COVID-19-Pandemie und dem Hochwasser in West- und Mitteleuropa im Sommer 2021 hat unter anderem Deutschland in jüngster Vergangenheit zwei schwerwiegende Krisenszenarien erlebt. Die Auswirkungen auf die Gesellschaft und Wirtschaft sind verheerend. Parallel lassen sich Krisenereignisse im digitalen Raum, wie die Zunahme an Cyberkriminalität beobachten. Es wird zunehmend deutlich, dass die Resilienz analoger sowie digitaler Prozesse wichtiger für die vollständige Betriebsfähigkeit wird. Die vorliegende Arbeit setzt sich mit der Bedeutung des Resilient Smart Farming (RSF) in Krisenzeiten als Möglichkeit für eine nachhaltige, umweltgerechte und resiliente digitale Landwirtschaft auseinander. Dazu wurden u.a. lokale Schadensmeldungen gruppiert und mögliche RSF-Gegenmaßnahmen aufgezeigt. Im Ergebnis zeigt sich eine Bewertung von Konzepten des RSF hinsichtlich der Krisenprävention und -bewältigung anhand aktueller realer Beispiele. Aufgrund zunehmender Bedrohungen durch Naturkatastrophen und Cyberkriminialität gehen wir davon aus, dass die Aufmerksamkeit von Gesellschaft und Politik für die Resilienz der Primärproduktion weiter steigen wird.},

abstract = {Technological progress can disrupt domains
and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

For example, if a farmer is in the field during a network outage, such as a failure of the mobile network, an alternative communication channel is needed to continue to connect to IT components and required data. With increasing digitalization, Low Power Wide Area Network (LPWAN) technologies are being used more and more frequently, e.g. for sensor networks. The LPWAN technologies offer a high range and can be used autonomously for the most part, but do not allow classic TCP/IP communication. In this work, a popular LPWAN technology, namely LoRaWAN, is experimentally supplemented by AX.25 on OSI layer 2 (Data Link Layer) to allow end devices TCP/IP-based communication over long distances. The evaluation shows that classic low-bandwidth applications are thus functional and can enable reliable, crisis-capable data transmission.},

Sollte sich ein Landwirt beispielsweise während eines lokalen Krisenfalls, wie einem Ausfall des Mobilfunknetzes oder des Internetzugangs des Betriebs, auf dem Feld aufhalten, wird ein alternativer Kommunikationskanal benötigt, um weiterhin eine Verbindung zu IT-Komponenten und benötigten Daten herstellen zu können. Mit der zunehmenden Digitalisierung finden Low-Power-Wide-Area-Network (LPWAN)-Technologien immer häufiger Anwendung, beispielsweise durch den Aufbau von Sensornetzwerken. Die eingesetzten LPWANTechnologien bieten dabei eine hohe Reichweite und sind größtenteils autark einsetzbar, erlauben jedoch keine klassische TCP/IP-Kommunikation. Im Rahmen dieser Arbeit wird experimentell eine populäre LPWAN-Technologie, namentlich LoRaWAN, durch AX.25 auf OSI-Schicht 2 (Data Link Layer) ergänzt, um Endgeräten eine TCP/IP-basierte Kommunikation über weite Strecken zu erlauben. Die Evaluation zeigt, dass klassische Anwendungen mit niedriger Bandbreite somit funktionsfähig sind und krisentaugliche Datenübertragung in landwirtschaftlichen Betrieben ermöglichen können.},

So-called Smart Farming uses drones and a variety of sensors to measure climate, irrigation, soil moisture or GPS position. With this rapid influx of technology increases the threat that vulnerabilities in those technologies are being exploited for malicious intent. To show the impact of cyberattacks on agriculture, we present a simulation of several attacks on a ZigBee-based wireless sensor network. We conduct a delay attack, an interference attack and three different routing attacks (sinkhole, blackhole and selective forwarding attack). Those attacks are simulated using NETA with the OMNET++ framework. We will show that the security of WSN is influenced by factors like energy consumption or computation power, which can conflict with other interests like low per-unit costs.},

One possibility to manage data and use them to create value is the blockchain-technology. It is primary enforced by the food industries and consumers to ensure traceability and transparency. To put blockchain-technology into beneficial use in agriculture, this domain has to be analyzed regarding social and business aspects. This paper presents the results of a qualitative study where 41 actors from the agricultural do-main participated in focus groups and delivered a written statement. It was found that farmers are interested in adapting new markets and technologies early to get an economic advantage. On the other hand, the fear of losing traditional local business partners and the social surroundings of the farmers must be considered},

This paper examines the notions of resilience, adaption and transition within communication networks with a specific focus on crises. Based on a structured literature review, the fundamentals of resilience and communication networks are introduced. The paper then discusses the characteristics of (a) evolvability, accessibility, usability and diversity as well as (b) self-organization, -management, -optimization, - monitoring, -healing and -protection for communication network resilience. Finally, it outlines challenges and potentials of communication network resilience based in the use cases of security and crises.},
