Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces limits on consecutive unsuccessful logon attempts and account lockout duration, eliminating the inadequate lockout setting that enables brute-force attacks in this CVE.

prevent

Requires definition and enforcement of account lockout parameters as part of account management, directly addressing the missing or weak lockout configuration described in the CVE.

prevent

Enforces access-control decisions that include lockout state checks before granting authentication, preventing continued brute-force attempts once the account is locked.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-03 mostly match
prevents

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

DE.CM-03 partial match
prevents

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

PR.PS-04 partial match
prevents

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

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

CAPTCHA, account lock-out after repeated failures, and alerts on excessive attempts directly stop automated brute-force guessing of credentials.
