Post-Incident Review
Post-Incident Review: A structured review that captures causes, decisions, outcomes, and lessons after an incident. Roles, decision authority, evidence, communication, and timing should be defined before an incident occurs.
How it works and where it fits
Post-Incident Review belongs to a prepared workflow for handling security-relevant events. A technical signal becomes a substantiated incident only through triage, context, and assessment. Roles, decision authority, escalation paths, and stopping conditions should therefore be agreed in advance so actions remain consistent under time pressure.
Practical security relevance
Execution must balance rapid containment with careful evidence preservation. Actions should not unnecessarily destroy important traces or disrupt business operations without control. Timelines, decisions, and changes are documented; after recovery, root causes, identified gaps, and lessons learned feed back into controls, detection logic, and response plans.
