Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Enforces approved authorizations for logical access to stored information, directly stopping unauthorized read/write.

Requires protection of confidentiality/integrity for information at rest, directly addressing insecure storage.

Limits privileges so only authorized accesses to sensitive stored data are permitted.

Associates security attributes with information to support proper access decisions on storage.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

A.7.14 addresses end-of-life physical destruction, sanitization or label removal on equipment/media already containing data; it does not stop the product from storing sensitive information without limiting unauthorized read/write access in the first place.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-922, a class-level weakness. Rules are authored against its narrower children: CWE-312.
