    Performing a More Realistic Safety Analysis by Means of the Six-Variable Model
    (Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Ulfat-Bunyadi, Nelufar; Hatebur, Denis; Heisel, Maritta
    Safety analysis typically consists of hazard analysis and risk assessment (HARA) as well as fault tree analysis (FTA). During the first, possible hazardous events are identified. During the latter, failure events that can lead to a hazardous event are identified. Usually, the focus of FTA is on identifying failure events within the system. However, a hazardous event may also occur due to invalid assumptions about the system’s environment. If the possibility that environmental assumptions turn invalid is considered during safety analysis, a more realistic and complete safety analysis is performed than without considering them. Yet, a major challenge consists in eliciting first the ‘real’ environmental assumptions. Developers do not always document assumptions, and often they are not aware of the assumptions they make. In previous work, we defined the Six-Variable Model which provides support in making the ‘real’ environmental assumptions explicit. In this paper, we define a safety analysis method based on the Six-Variable Model. The benefit of our method is that we make the environmental assumptions explicit and consider them in safety analysis. In this way, assumptions that are too strong and too risky can be identified and weakened or abandoned if necessary.

    A user-centric approach to IT-security risk analysis for an identity management solution
    (Open Identity Summit 2022, 2022) Fähnrich, Nicolas; Winterstetter, Matthias; Kubach, Michael
    In order to build identity management (IdM) solutions that are secure in the practical application context, a holistic approach their IT-security risk analysis is required. This complements the indispensable technical, and crypto-focused analysis of risks and vulnerabilities with an approach that puts another important vector for security in the center: the users and their usage of the technology over the whole lifecycle. In our short paper we focus exclusively on the user-centric approach and present an IT-security risk analysis that is structured around the IdM lifecycle.
