Co-engineering Security and Safety Requirements for Cyber-Physical Systems

Co-engineering Security and Safety Requirements for Cyber-Physical Systems

Many safety critical systems, like transportation systems, are integrating more and more software based systems and are becoming connected. In some domains, such as automotive and rail, software is gradually taking control over human operations, and vehicles are evolving towards being autonomous. Such cyber-physical systems require high assurance on two interrelated properties : safety and security. In this context, safety and security can be co-engineered based on sound techniques borrowed from goal-oriented requirements engineering (RE).
