Documented procedures for detecting, responding to, and recovering from security incidents.
An Incident Response Plan (IRP) documents procedures for handling security incidents—detection, containment, eradication, recovery, and lessons learned. IRPs define roles and responsibilities, communication procedures, escalation paths, and technical response steps. Effective IRPs are tested through tabletop exercises and simulations. The plan ensures consistent, effective response regardless of who's available when incidents occur. IRPs are compliance requirements under most security frameworks.
Why It Matters
The DSC Perspective:
Incident response under pressure is not the time for improvisation. Documented, tested plans ensure consistent, effective response. Regular testing builds the muscle memory needed when real incidents occur.
