Post-incident review and updating detections centers on learning from what happened to improve future responses. In the incident lifecycle this phase focuses on analyzing the incident, identifying root causes, gaps in detection or containment, and what could be done better next time. The key outcome is actionable improvements to detection rules, alert logic, playbooks, and training so similar incidents are detected sooner and handled more effectively. The other phases serve different purposes: discovery and classification, stopping the spread, and restoring operations, while this phase wraps up with reflection and enhancement to prevent recurrence.
