A post-incident review is a systematic evaluation conducted after a security incident to analyze what occurred, why it happened, and how it can be prevented in the future. This process is crucial for refining incident response strategies, improving overall security posture, and ensuring lessons learned are integrated into future planning. It not only helps in identifying gaps in the response but also enhances team performance through shared experiences and accountability.
