A. B. C. D.D.
When preventative controls are not feasible, it means that there are risks that cannot be completely eliminated, reduced, or avoided. In this case, the most important action for an information security manager is to manage the impact of the risk.
Answer B: Manage the impact.
Managing the impact means taking steps to minimize the consequences of a potential security breach. This involves creating contingency plans and procedures to respond to incidents, such as incident response plans, business continuity plans, and disaster recovery plans. These plans should be tested and regularly reviewed to ensure they are up to date and effective.
Assessing vulnerabilities (Answer A) is important, but it does not necessarily lead to effective risk management. Identifying vulnerabilities is just the first step in the risk management process, and it is important to prioritize and focus on the vulnerabilities that pose the greatest risk.
Evaluating potential threats (Answer C) is also important, but it does not necessarily lead to effective risk management. Knowing the potential threats is just the first step in the risk management process, and it is important to prioritize and focus on the threats that are most likely to occur and have the greatest impact.
Identifying unacceptable risk levels (Answer D) is important, but it does not necessarily lead to effective risk management. Identifying unacceptable risk levels is just the first step in the risk management process, and it is important to take steps to manage and mitigate the risks to an acceptable level.
In summary, managing the impact of a potential security breach is the most important action for an information security manager to perform when preventative controls are not feasible. This involves creating and testing contingency plans and procedures to respond to incidents and minimize their consequences.
