    Towards Secure Urban Infrastructures: Cyber Security Challenges for Information and Communication Technology in Smart Cities
    (Mensch und Computer 2020 - Workshopband, 2020) Reuter, Christian; Haunschild, Jasmin; Hollick, Matthias; Mühlhäuser, Max; Vogt, Joachim; Kreutzer, Michael
    The growth of cities continues to be a global megatrend. As more and more people live in urban areas and urban services and infrastructures are under growing strain, technologies are increasingly being researched and used to make city life more efficient and comfortable. 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. 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.

    Website operators are not the enemy either - Analyzing options for creating cookie consent notices without dark patterns
    (Mensch und Computer 2022 - Workshopband, 2022) Stöver, Alina; Gerber, Nina; Cornel, Christin; Henz, Mona; Marky, Karola; Zimmermann, Verena; Vogt, Joachim
    Users frequently receive cookie consent notices when they enter a website. They are supposed to enable an informed decision about data collection. Instead, they often contain deceptive designs - also known as dark patterns - that can nudge users to consent and thus compromise their privacy. In this paper, we explore the causes of the widespread use of dark patterns in cookie consents. To do so, we take the perspective of website operators, who are responsible for the use of cookie consent notices and are increasingly making use of Consent Management Platforms (CMPs) to manage end-user consent. CMPs usually contain certain design templates. To find out whether it is possible for website operators to generate notices without dark patterns using CMPs, we analyzed a selection of the templates offered by major CMPs. We show that 60% of the notices created with default settings contain at least one dark pattern. A notice that does not nudge toward a certain choice could only be generated with 62.5% of the CMPs. Our results imply that the responsibility for privacy-friendly notices lies more with the CMPs than with the website operators.
