Summary
This chapter provided a comprehensive overview of risk assessment in the context of SIS cybersecurity, elucidating the fundamental principles, various methodologies, and practical execution of such assessments. It underscored the importance of identifying SuCs, detecting threats and vulnerabilities, determining the possible consequences and impacts, assessing inherent risk, and establishing SL-Ts.
This chapter also revealed the relevance and potential applications of risk assessment methodologies such as NAMUR, IEC 62443, BowTie, and NIST 800-82 in evaluating and mitigating SIS cybersecurity risks. It closely evaluated the iterative and dynamic process of effectively conducting risk assessments, highlighting the necessity for regular updates to stay responsive to emerging threats and changes in the operational environment.
Furthermore, it laid emphasis on the continuous nature of risk management, the need for re-evaluation of risks, and the requirement of ongoing attention...
