All CISM Test Inside Isaca Questions

The best way to determine corrective actions after a major information security incident is to conduct a postmortem assessment, which is a systematic and structured review of the incident, its causes, its impacts, and its lessons learned. A postmortem assessment can help to identify the root causes of the incident, the strengths and weaknesses of the incident response process, the gaps and deficiencies in the security controls, and the opportunities for improvement and remediation. A postmortem assessment can also help to document the recommendations and action plans for preventing or minimizing the recurrence of similar incidents in the future.

Performing post-incident reviews is the best way to enhance training for incident response teams because it allows them to identify the strengths and weaknesses of their response, learn from the lessons and best practices, and implement corrective actions and improvement plans for future incidents. Post-incident reviews also help to evaluate the effectiveness and efficiency of the incident response process and procedures, and to update them as needed.

References: The CISM Review Manual 2023 states that “post-incident reviews are an essential part of the incident response process” and that “they provide an opportunity to assess the performance of the incident response team, identify areas for improvement, and document lessons learned and best practices” (p. 191). The CISM Review Questions, Answers & Explanations Manual 2023 also provides the following rationale for this answer: “Performing post-incident reviews is the best way to enhance training for incident response teams, as it enables them to learn from their experience and improve their skills and knowledge” (p. 97).

Engaging stakeholders is the most important step when developing an information security strategy, as it ensures that the strategy is aligned with the business objectives, risks, and needs of the organization. Stakeholders include senior management, business units, IT staff, customers, regulators, and other relevant parties who have an interest or influence on the information security of the organization. By engaging stakeholders, the information security manager can gain their support, input, feedback, and buy-in for the strategy, as well as identify and prioritize the security requirements, expectations, and challenges.
