Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-307

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

addresses: CWE-307

Specific conditions can include excessive failed attempts, triggering stronger authentication that restricts brute-force exploitation.

DE.CM-03 partial match
blocks

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

PR.AA-03 partial match
blocks

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

PR.PS-04 partial match
blocks

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