Automotive Domain: Towards Bringing System Design, Functional Safety, and Cybersecurity Together

Yuri Gil Dantas, GmbH

Prioritizing the safety and security of vehicle systems is essential for addressing potential issues in the concept phase of vehicle development. To this end, automotive disciplines, such as system design, functional safety, and cybersecurity, play pivotal roles. System design establishes the foundations for other disciplines by, e.g., identifying, specifying, and seamlessly integrating domains, subdomains, and components into the overall vehicle architecture. Standards, such as ISO 26262 and ISO 21434, mandate that functional safety and cybersecurity activities are performed during the concept phase. The goal of such activities is to minimize the risk of, e.g., accidents arising from either malfunctioning system behavior (functional safety), or intentional attacks carried out by malicious actors (cybersecurity). In many cases, the activities related to system design, functional safety, and cybersecurity are interconnected and relevant to each other. However, in the current state of practice, such activities are carried out independently, lacking a clear handover of artifacts from one discipline to the other. This independent approach may lead to inefficiencies due to potential duplication of work, and potential gaps or inconsistencies due to the lack of interactions between different disciplines. Establishing strong connection and interaction points among system design, functional safety, and cybersecurity is crucial for efficient work and for ensuring the overall safety and
