Analysis conducted after incidents to identify lessons learned and improve future response.
Post-incident review (or lessons learned) analyses completed incidents to identify what worked, what didn't, and how to improve. Reviews examine detection effectiveness, response timeliness, communication quality, and recovery success. Findings should drive concrete improvements—updated procedures, additional controls, or training needs. Blameless reviews focus on process improvement rather than individual fault. Documentation enables knowledge sharing across the organisation.
Why It Matters
The DSC Perspective:
Every incident is a learning opportunity. Conduct thorough reviews and act on findings. Organisations that learn from incidents get stronger; those that don't repeat the same mistakes.
