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-285 CWE-266

Documented procedures facilitate correct implementation and ongoing management of authorization decisions.

addresses: CWE-285 CWE-266

Periodic reviews identify and correct flaws in authorization decisions or enforcement.

addresses: CWE-285 CWE-266

Specifying access authorizations for each account and requiring approvals for account requests enforces proper authorization decisions.

addresses: CWE-266 CWE-285

The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.

addresses: CWE-266 CWE-285

Ensures privileges are assigned only as necessary rather than incorrectly over-granted.

addresses: CWE-285

The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.

addresses: CWE-285

Establishing permitted attributes and values, plus auditing changes, ensures authorization decisions are based on correctly managed policy data.

addresses: CWE-285

Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.
