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.

addresses: CWE-613

Locks the device (typically after inactivity) until re-authentication, addressing insufficient session expiration by preventing indefinite access.

addresses: CWE-613

Automatically terminating sessions after a defined period directly enforces session expiration, preventing indefinite session lifetimes that attackers can exploit.

addresses: CWE-922

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

addresses: CWE-922

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

addresses: CWE-922

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

addresses: CWE-613

Re-authentication after inactivity or time-based triggers prevents indefinite use of potentially hijacked or stale sessions.

addresses: CWE-613

Terminating sessions and network connections upon completion prevents insufficient session expiration.

addresses: CWE-922

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