Click on the arrows to vote for the correct answer
A. B. C. D.B.
As an IS auditor, evaluating a cybersecurity incident response plan would involve assessing various aspects of the plan to determine its effectiveness in mitigating potential security threats. However, some factors are more critical than others in ensuring the plan's success.
Of the options given, the IS auditor's greatest concern would be the absence of incident response metrics (Option D). Incident response metrics refer to the measures used to assess the effectiveness of the plan in mitigating cybersecurity incidents. They include the time taken to identify and contain an incident, the amount of data lost, the cost of responding to the incident, among others.
Without incident response metrics, it would be challenging to evaluate the effectiveness of the cybersecurity incident response plan in addressing security incidents. Incident response metrics provide a benchmark for measuring the plan's performance and identifying areas that need improvement. Furthermore, incident response metrics enable the organization to track the progress of the incident response plan over time and improve it as necessary.
While the other options (Option A, B, and C) are also essential considerations when evaluating a cybersecurity incident response plan, they do not carry as much weight as the absence of incident response metrics. For instance, if the plan has not been recently tested (Option A), the organization can schedule testing to assess the plan's efficacy. If roles and responsibilities are not adequately defined (Option B), the organization can provide training to ensure everyone understands their roles. If stakeholder contact details are not up-to-date (Option C), the organization can update them as necessary.
In summary, the IS auditor's greatest concern when evaluating a cybersecurity incident response plan is the absence of incident response metrics. Incident response metrics provide a benchmark for measuring the plan's effectiveness and identifying areas that need improvement. The other options (plan testing, role definition, and stakeholder contact details) are essential but not as critical as incident response metrics.
