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.
Tracking information locations and access supports secure storage practices instead of insecure ones.
Establishing an alternate site with equivalent protections directly mitigates insecure storage of sensitive backup information.
Requiring protection of backup information directly addresses insecure storage of sensitive data in backups.
Policy explicitly addresses insecure storage of CUI on external systems, requiring compliant handling and protections.
Proper categorization drives selection of storage controls that keep sensitive information from being stored insecurely.
The control explicitly requires secure storage mechanisms for sensitive information, closing the insecure-storage weakness class.
Storing information as fragments on distinct components is an architectural control that avoids insecure single-location storage of the complete sensitive data set.
OPSEC requirements improve handling and storage practices for sensitive supply-chain information.
