AC-14 directly mitigates CWE-306 by requiring organizations to identify, authorize, and limit critical functions accessible without identification or authentication, preventing unauthenticated remote exploitation in CVE-2025-62582.
IA-8 mandates unique identification and authentication for non-organizational users, blocking the unauthenticated network access that enables high-impact compromise in this CVE.
AC-3 enforces approved access authorizations including authentication requirements, ensuring critical DIAView functions are protected against unauthorized logical access.
