Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

CM-12 Information Location
addresses: CWE-922

Tracking information locations and access supports secure storage practices instead of insecure ones.

CP-6 Alternate Storage Site
addresses: CWE-922

Establishing an alternate site with equivalent protections directly mitigates insecure storage of sensitive backup information.

CP-9 System Backup
addresses: CWE-922

Requiring protection of backup information directly addresses insecure storage of sensitive data in backups.

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-922

Policy explicitly addresses insecure storage of CUI on external systems, requiring compliant handling and protections.

RA-2 Security Categorization
addresses: CWE-922

Proper categorization drives selection of storage controls that keep sensitive information from being stored insecurely.

SC-28 Protection of Information at Rest
addresses: CWE-922

The control explicitly requires secure storage mechanisms for sensitive information, closing the insecure-storage weakness class.

SI-23 Information Fragmentation
addresses: CWE-922

Storing information as fragments on distinct components is an architectural control that avoids insecure single-location storage of the complete sensitive data set.

SR-7 Supply Chain Operations Security
addresses: CWE-922

OPSEC requirements improve handling and storage practices for sensitive supply-chain information.
