Framework: The Center for Internet Security (CIS) Top 18 Controls

Safeguard 11.2 requires organizations to test their data recovery capabilities on a regular basis, validating that backup systems and restoration procedures function as intended. Backups only hold value if they can be successfully restored when needed. Testing confirms data integrity, verifies procedural accuracy, and reveals gaps in both technology and human readiness. The safeguard calls for quarterly recovery tests—or more frequent exercises for critical systems—covering a representative sample of enterprise assets. Testing should confirm that restored systems are fully operational, data is complete, and recovery times align with documented Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs). Regular testing prevents false confidence in backups and ensures that teams remain proficient under pressure during actual incidents.

Implementing this safeguard involves defining clear objectives, scope, and success criteria for each test. Recovery exercises can range from small-scale file restoration to full disaster recovery simulations involving multiple systems. Documentation of test results, lessons learned, and corrective actions provides an audit trail and supports continuous improvement. Automation tools can assist in verifying backup integrity by performing checksum validation and generating reports. In hybrid or cloud environments, testing must include restoring data across different platforms to validate cross-compatibility. Organizations should treat recovery tests not as routine checkboxes but as operational rehearsals that build confidence and resilience. When executed consistently, this safeguard ensures that recovery processes evolve alongside the enterprise, guaranteeing that when data loss or corruption occurs, restoration is not a theoretical plan but a proven, repeatable capability.
