Questions: A security analyst working for a large financial institution became concerned about a security incident that could compromise sensitive customer information. As part of the incident response process, their team conducted a tabletop exercise to identify areas for improvement in the incident response plan. What is the purpose of reviewing lessons learned after a security incident? To gather forensic evidence To simulate a real-world security incident To train staff members on incident response procedures To identify weaknesses in the incident response plan

The answer is the last one: To identify weaknesses in the incident response plan.

Explanation for each option:

• To gather forensic evidence: This is not the primary purpose of reviewing lessons learned. Gathering forensic evidence is typically part of the incident investigation process, not the post-incident review.

• To simulate a real-world security incident: Simulating a real-world security incident is the purpose of a tabletop exercise itself, not the review of lessons learned. The exercise helps prepare the team for actual incidents.

• To train staff members on incident response procedures: While training staff is an important part of incident response, the review of lessons learned is more focused on evaluating the effectiveness of the response and identifying areas for improvement.

• To identify weaknesses in the incident response plan: This is the correct answer. Reviewing lessons learned after a security incident helps the organization identify weaknesses or gaps in the incident response plan, allowing them to make necessary improvements to better handle future incidents.

In summary, the purpose of reviewing lessons learned after a security incident is to identify weaknesses in the incident response plan.
