The Disaster Recovery Plan (DRP) (A) is the document that should incorporate incident handling procedures during the planning phase. It details how to respond to and recover from incidents to restore normal operations.
Access control policy (B) governs permissions.
Backup policy (C) describes data backup processes but not incident handling.
Vulnerability report (D) is an assessment document, not a procedural plan.
GICSP underscores integrating incident response within disaster recovery planning to ensure comprehensive preparedness.
