    Risk-Oriented Security Engineering
    (Automotive - Safety & Security 2017 - Sicherheit und Zuverlässigkeit für automobile Informationstechnik, 2017) Ebert, Christof
    Virtually every connected system will be attacked sooner or later. A 100% secure solution is not feasible. Therefore, advanced risk assessment and mitigation is the order of the day. Risk-oriented security engineering for automotive systems helps in both designing for robust systems as well as effective mitigation upon attacks or exploits of vulnerabilities. Security must be integrated early in the design phase of a vehicle to understand the threats and risks to car functions. The security analysis provides requirements and test vectors and adequate measures can be derived for balanced costs and efforts. The results are useful in the partitioning phase when functionality is distributed to ECUs and networks. We will show with concrete examples how risk-oriented cyber security can be successfully achieved in automotive systems. Three levers for automotive security are addressed: (1) Product, i.e., designing for security for components and the system, (2) Process, i.e., implementing cyber security concepts in the development process and (3) Field, i.e., ensuring security concepts are applied during service activities and effective during regular operations.

    Views on Quality Requirements in Academia and Practice: Commonalities, Differences, and Context-Dependent Grey Areas
    (Software Engineering 2021, 2021) Vogelsang, Andreas; Eckhardt, Jonas; Mendez, Daniel; Berger, Moritz
    This article originally appeared in Information and Software Technology (IST). Context: Quality requirements (QRs) are a topic of constant discussions both in industry and academia. While many academic endeavors contribute to the body of knowledge about QRs, practitioners may have different views. Objective: We report on a study to better understand the extent to which available research statements on QRs from academic publications, are reflected in the perception of practitioners. Our goal is to analyze differences, commonalities, and context-dependent grey areas in the views of academics and practitioners. Method: We conducted a survey with 109 practitioners to assess their agreement with the selected research statements about QRs. Based on a statistical model, we evaluate the impact of a set of context factors to the perception of research statements. Results: Our results show that a majority of the statements is well respected by practitioners; however, not all of them. When examining the different groups of respondents, we noticed deviations of perceptions that lead to new research questions. Conclusions: Our results help identifying context-dependent differences about how academics and practitioners view QRs and statements where further research is useful.
