Official Requirement
Protect the confidentiality of backup CUI at storage locations.
What This Means in Plain English
Backup copies of CUI must be protected with the same level of security as the original data. Backup storage locations must have physical and logical access controls, and backup data should be encrypted.
How Petronella Implements This Control
Petronella Technology Group implements this control through:
- Veeam backup encryption using AES-256 for all backup jobs containing CUI
- Backup storage in access-controlled server rooms with badge access and logging
- Off-site backup copies encrypted before transmission and stored at a secure facility
- Backup access restricted to designated backup administrators only
- ComplianceArmor tracking backup storage locations, encryption status, and access controls
Assessment Guidance
Assessors will verify that backup data is encrypted, check physical security of backup storage locations, review access controls on backup systems, and confirm that off-site backups have equivalent protection to primary data.
Common Implementation Gaps
- Backup data stored unencrypted
- Backup tapes in unsecured locations
- Off-site backups without physical security controls
- Backup access not restricted to authorized personnel
- No encryption for cloud backup storage
