Mitigating Controls

Likely Mitigating Controls AI

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.

The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.

Implements core proper privilege management by restricting to only required rights.

The awareness and training policy mandates training on access control practices, directly reducing the likelihood of improper access control weaknesses being introduced or exploited.

Training covers proper privilege management practices, making incorrect privilege assignments less likely.

Certification requires independent assessment confirming access controls are implemented correctly and effective.

Baseline includes documented access control settings that are reviewed and maintained, reducing the ability to exploit improper access control.

Enforces access controls and oversight on who can propose, approve, or implement configuration modifications.

Reviewing changes for security impacts prevents introduction of improper privilege assignments or escalations.
