Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

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

SC-28 Protection of Information at Rest good match

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

AC-6 Least Privilege good match

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

AC-16 Security and Privacy Attributes partial match

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.

A.7.14 Secure disposal or re-use of equipment none match
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.
