CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-287Improper Authentication4,757Mandates unique identification and authentication of non-organizational users, directly mitigating improper authentication.
CWE-306Missing Authentication for Critical Function2,600Requires authentication for non-organizational users, preventing access to critical functions without proper identification and authentication.
CWE-290Authentication Bypass by Spoofing642Unique identification of non-organizational users reduces the feasibility of authentication bypass by spoofing.
CWE-288Authentication Bypass Using an Alternate Path or Channel534Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.
CWE-302Authentication Bypass by Assumed-Immutable Data35Proper authentication for non-organizational users counters bypasses relying on assumed-immutable data.
CWE-304Missing Critical Step in Authentication32Ensures the authentication process is followed for non-organizational users, avoiding missing critical steps.
