Summary

This chapter has provided a comprehensive overview of the ISO/SAE 21434 standard and the crucial role it plays in implementing a systematic cybersecurity engineering approach to developing automotive systems. By delving into the intricacies of the V-model life cycle stages and demonstrating how they are interdependent, we have highlighted the importance of following the secure-by-design approach at every step of the product engineering process. As we have shown, cybersecurity activities must be embedded into that process from start to finish, rather than being bolted on as an afterthought. Our discussion has emphasized the significance of understanding the various work products associated with the standard and how they can be leveraged to achieve a secure system. Furthermore, we have illustrated how the standard’s cybersecurity activities are relevant throughout the system’s lifespan, from planning to end of life.

In summary, the insights provided in this...
