Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates the authentication bypass vulnerability by requiring timely remediation of known flaws through vendor patches as specified in the Broadcom advisory.

IA-2 Identification and Authentication (Organizational Users) good match
prevent

Ensures organizational users are uniquely identified and authenticated, directly countering the improper authentication mechanism that allows bypass.

AC-3 Access Enforcement good match
prevent

Mandates enforcement of approved authorizations following successful authentication, preventing unauthorized access to sensitive data despite the bypass flaw.
