    Satisfying and Efficient Privacy Settings
    (Mensch und Computer 2018 - Tagungsband, 2018) Rudolph, Manuel; Polst, Svenja
    Data protection is becoming increasingly important for users of digital services. Recent studies show that users are concerned that they have too little control over their personal data. However, users also complain that current interfaces for specifying privacy and security settings are too time-consuming and complicated. Therefore, we first identified the existing ways to configure these settings. Then, we experimentally examined which way of specification is best suited for a certain user type in terms of satisfaction or efficiency. Regarding efficiency, the type of specification with the smallest number of options, called security level, is best suited for all users. Regarding satisfaction, there is not a single type of specification that fits all user types, but different user types prefer different types of specification.

    Usable Security Policy Specification
    (Mensch und Computer 2016 – Workshopband, 2016) Rudolph, Manuel; Feth, Denis
    Security policies determine which security requirements have to be met in a domain and how they are implemented organizationally and/or technically. However, their specification at run-time poses a challenge for policy authors (e.g., IT administrators or end users), especially if they are inexperienced in this task. Thus, specification interfaces have to guide the policy author during the specification process. However, matching appropriate specification processes to the policy authors’ individual needs is challenging due to a high variability in the authors’ skill levels and security perceptions. In this paper, we identify existing specification approaches, derive generic specification paradigms and show the feasibility of one of them in an industrial case study.
