Incident Response & Postmortems
Incident Response & Postmortems refer to the structured processes organizations follow when handling unexpected security breaches, system failures, or operational disruptions. Incident response involves immediate actions to identify, contain, and resolve the incident, minimizing damage and restoring normal operations. Postmortems are thorough reviews conducted after the incident to analyze causes, assess response effectiveness, and document lessons learned. This approach helps organizations improve future preparedness, reduce risks, and foster a culture of continuous improvement and accountability.
