The risk practitioner’s best recommendation after recovery steps have been completed is B. Perform a root cause analysis. A root cause analysis is a process of identifying and assessing the underlying causes of a problem or an incident. By performing a root cause analysis, the risk practitioner can help the organization to understand how and why the cyber attack happened, what vulnerabilities and gaps were exploited, and what actions and controls can be implemented to prevent or mitigate similar incidents in the future12
A root cause analysis can also help the organization to improve its incident response plan, which is a set of instructions to help IT staff detect, respond to, and recover from network security incidents3 A root cause analysis can provide valuable feedback and lessons learned from the cyber attack, and help the organization to update and test its incident response plan accordingly45
Developing new key risk indicators, recommending the purchase of cyber insurance, and reviewing the incident response plan are all possible actions that the risk practitioner can take after a cyber attack, but they are not the best recommendation. Developing new key risk indicators can help the organization to monitor and measure its risk exposure and performance, but it does not address the root causes of the cyber attack12 Recommending the purchase of cyber insurance can help the organization to hedge against the financial losses caused by cyber incidents, but it does not prevent or solve the underlying issues67 Reviewing the incident response plan can help the organization to evaluate its effectiveness and identify areas for improvement, but it does not explain how and why the cyber attack occurred345
Therefore, the best recommendation is to perform a root cause analysis, as it can help the organization to understand, resolve, and prevent the cyber attack and its consequences12
