    The Implementation of Protective Measures and Communication of Cybersecurity Alerts in Germany - A Representative Survey of the Population
    (Mensch und Computer 2022 - Workshopband, 2022) Kaufhold, Marc-André; Bäumler, Julian; Reuter, Christian
    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.

    The Notion of Relevance in Cybersecurity: A Categorization of Security Tools and Deduction of Relevance Notions
    (Mensch und Computer 2022 - Workshopband, 2022) Kuehn, Philipp; Bäumler, Julian; Kaufhold, Marc-André; Wendelborn, Marc; Reuter, Christian
    Proper cybersecurity requires timely information to defend the IT infrastructure. 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.
