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.
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.
