CWE Name CVEs Why this control addresses it
CWE-862Missing Authorization11,800+Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
CWE-284Improper Access Control8,100+Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
CWE-306Missing Authentication for Critical Function3,900+Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
CWE-285Improper Authorization1,700+The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication.
