CVE-2023-44096

Requires adaptive authentication under specific conditions, directly strengthening authentication mechanisms against improper or insufficient authentication.

This control directly enforces limits on consecutive invalid logon attempts and automatic response (e.g., lockout) to prevent brute-force exploitation of authentication mechanisms.

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.

Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.

Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.

Generating auth logs enables later detection or forensics but does not itself restrict attempts.

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.
