Engineering cyber-physical systems secure by design requires engineers to consider security from the ground up. However, current systems engineering processes are not tailored to cyber-physical systems, or lack an integration with security engineering. In this paper, we integrate secure software engineering practices into an engineering process for cyber-physical systems. Thereby, we enable engineers to specify security requirements at the level of systems engineering, and to take effective countermeasures during both platform-independent and platform-specific software engineering. Our key contribution is the integration of threat models for tracing security requirements to countermeasures. We illustrate our approach by an autonomous car with high security requirements.
