During which phase of the incident management life cycle does the response team formally review the incident, document how effective its actions were, capture what went well, and record recommendations for improvement to strengthen future responses?
The lessons learned phase occurs after containment, eradication, and recovery are complete. The response team conducts a structured review to measure the effectiveness of its actions, identify successes and shortcomings, and document actionable recommendations. This retrospective feeds updates to the incident response plan, playbooks, security controls, and training, enhancing the organization's ability to handle future incidents. By contrast, an incident response plan is part of preparation, remediation happens during containment and eradication, and chain of custody concerns evidence handling, not post-incident analysis.
