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.
Security training teaches access control policies and enforcement, reducing improper access control implementations.
Authorization servers centrally manage access rights, preventing improper access control.
Central management enforces consistent access-control policies across systems, reducing the likelihood of missing or inconsistent enforcement.
Resources allocated to security programs enable proper design, implementation, and maintenance of access control mechanisms.
Screening criteria tied to position sensitivity limit the set of individuals who can be granted access, shrinking the attack surface for improper access control weaknesses.
Threat hunting directly searches for indicators of unauthorized access or control violations that bypassed preventive mechanisms.
Defining security roles/responsibilities and integrating risk management into the SDLC directly reduces improper access control by ensuring access decisions are designed and reviewed throughout development.
Guidance on effective use of access control mechanisms and known configuration vulnerabilities makes improper access control harder to exploit.
