Summary

This chapter explored the similarities and differences between safety and security engineering approaches, highlighting the importance of taking an integrated approach to these two disciplines. First, this chapter focused on the process impacts and the need to extend existing safety and quality processes to satisfy the cybersecurity engineering approach. We then discussed the unique areas of each domain, emphasizing the need to increase safety and security literacy to understand how safety engineering focuses on identifying and managing risks that prevent accidents, while security engineering focuses on identifying and mitigating threats that prevent intentional harm. Conflicts between safety and security can arise, and this chapter presented strategies for resolving these conflicts. Similarly, many areas of synergies were explored throughout the concept, design, implementation, and testing phases. Several examples were shown in which safety reinforces the security properties...
