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

The remaining safeguards within Control 11 establish a comprehensive framework for secure, reliable data recovery. They include protecting recovery data with equivalent security controls as production data, maintaining an isolated instance of backups, and ensuring encryption and access control mechanisms safeguard stored copies. These measures guarantee that recovery repositories themselves do not become attack targets. Backups must be shielded from ransomware and insider threats by using segregation techniques such as air-gapped systems, immutable storage, or dedicated recovery networks. Additionally, maintaining detailed inventories of recovery data and implementing multi-factor authentication for backup management interfaces help prevent unauthorized manipulation or deletion. Collectively, these safeguards align data recovery with broader cybersecurity principles of confidentiality, integrity, and availability.

Operationalizing these safeguards requires thoughtful design and continuous oversight. Backup infrastructure should undergo the same security hardening, patching, and monitoring applied to production systems. Network segmentation ensures that compromised environments cannot directly access recovery repositories. Logging and audit trails provide visibility into backup operations and detect unusual activity, such as mass deletions or unauthorized access. Documentation of recovery processes, storage locations, and encryption methods ensures consistency and transparency across the organization. Periodic reviews validate that recovery methods remain compatible with current technologies and meet compliance mandates. Together, the remaining safeguards elevate data recovery from a reactive last resort to a fully integrated component of enterprise resilience—one capable of restoring trust, preserving operations, and proving that security maturity extends beyond prevention to reliable restoration.
