Disaster recovery plans must be regularly tested because an untested plan cannot be trusted for exams or real-world operations. Learn the range of test types—from plan review and tabletop simulations to execution, parallel runs, and full interruption tests—and balance assurance against cost when choosing the right level. #CISSP #ISC2
Keypoints
- A disaster recovery plan is useless unless it is regularly tested.
- Testing types progress from low-cost reviews to high-cost full interruption exercises.
- Tabletop and simulation exercises validate decision-making and coordination without executing systems.
- Execution, parallel runs, and full interruption tests validate real recovery but carry higher risk and expense.
- Always complete each testing level before moving to the next to build reliable assurance.
