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.
System audit review detects violations of access controls by identifying unauthorized access attempts.
The team provides specialized analysis of access-related incidents, enabling quicker identification and response to unauthorized access attempts.
Explicit security control assessments verify proper access control enforcement, detecting weaknesses that the flaw remediation process then eliminates.
Resiliency goals and objectives routinely incorporate least-privilege and access-control maintenance under adverse conditions, reducing improper access control.
Role separation implements access control boundaries between internal and external name resolution services.
Distribution forces an attacker to compromise multiple independent components rather than a single centralized target, directly reducing the impact of access control failures.
Directly detects unauthorized local/network/remote connections and system use that result from improper access control.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
