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.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Prevents overly permissive assignments to critical resources by limiting to task needs.
The awareness and training policy mandates training on access control practices, directly reducing the likelihood of improper access control weaknesses being introduced or exploited.
Security training teaches access control policies and enforcement, reducing improper access control implementations.
The control directly enforces access controls to prevent unauthorized access, modification, or deletion of audit information and tools.
Control assessments verify that access controls are implemented correctly and operating as intended, detecting improper access control before exploitation.
Certification requires independent assessment confirming access controls are implemented correctly and effective.
