To make well-informed cybersecurity risk decisions, it is most important to determine and understand the risk rating of scenarios. A risk rating is a measure of the severity and priority of a risk, based on the combination of its impact and likelihood. A risk scenario is a description of a potential event or situation that could adversely affect the organization’s objectives, assets, or processes. By determining and understanding the risk rating of scenarios, the organization can identify the most critical and urgent risks, and select the appropriate risk response strategies accordingly. The other options are not as important as determining and understanding the risk rating of scenarios, because they do not provide a clear and comprehensive view of the risk, butrather focus on specific or partial aspects of the risk management process. References = Risk and Information Systems Control Study Manual, Chapter 2, Section 2.3.1, page 45.
