Functional safety and cyber security must be systematically developed and implemented in parallel. Currently this is often done in piecemeal, as industry standards and methods for safety and security are quite isolated from each other. This previously established separation of the two "disciplines" each with its own standards and procedures is not sustainable because of dependencies and mutual influences are overlooked. In addition, a separate procedure is inefficient because many functions have to be touched several times. Essential is an integrated approach for the development and verification of requirements in order to make these two quality requirements manageable.
We show in this presentation the systematic and continuous development and implementation of safety and security requirements. Hella corporation illustrates the method and advantages of such combined safety and security approach using the example of ADAS (Advanced Driver Assistance System). The article thus gives a good overview of the methodology and the art of integrated engineering for Safety and Cybersecurity. At the same show our industry experience, as the methodology is implemented effectively. Many lessons learned from practical help to transfer in their own environment of the participants.
