CVE-2023-4501

Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.

Detects unauthorized successful logons resulting from improper authentication implementations.

Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.

Security awareness training instructs users on secure authentication practices and avoiding credential compromise.

Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.

Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.

Session content review can reveal authentication bypasses or failures in session establishment.

Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.

Identifying and recording vulnerabilities catches the primary weaknesses that allow authentication bypass.

Strong authentication mechanisms and policy enforcement directly reduce bypass opportunities arising from implementation flaws.

Secure SDLC practices directly enforce proper error-handling and return-value checking during development.

Mandating segregated approval and oversight for non-human identities reduces the chance that weak or orphaned credentials can be exploited for unauthorized authentication.

A.5.17 directly mandates generation of non-guessable unique secrets, secure transmission, immediate change of defaults/temporary creds, strong password enforcement, no-reuse, and compromise response, which stops most improper-authentication exploits at source; the bounded remainder is non-password authentication methods and sufficiency-of-proof cases (e.g. IA-2/IA-5 enhancements) left to other controls.
