On the one hand, the increasing complexity and connectivity due to the evolution of driver assist functions up to autonomously driving vehicles and their additional connection to external networks is a challenge for safety and security. Generally, we assume that a secure environment is a precondition for safety. On the other hand, the implementation of security measures could lead to violations of safety and introduced safety measures may also have an additional security impact. A close cooperation between the domains safety and security is mandatory for developing safe and secure systems and can be supported by wellestablished analysis techniques. Therefore, we propose suitable process interfaces between both domains, as well as appropriate methods and related work products for cooperation. In our publication, we demonstrate how to systematically reuse the safety analyses outputs in the security domain in a five-step approach and how to analyze the impact of security measures in the safety context. With our approach the completeness, correctness, and consistency of safety and security analyses will be improved. |
