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.
Detects unauthorized successful logons resulting from improper authentication implementations.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Documented IA policy and procedures require proper authentication mechanisms to be defined and followed, reducing improper authentication.
Identity providers centralize and enforce authentication mechanisms, reducing improper authentication.
Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.
Hunting detects anomalous authentication patterns or successful bypasses that allow persistent unauthorized entry.
Requiring explicit security roles and risk integration in the SDLC forces authentication mechanisms to be planned, documented, and validated instead of omitted or weakly implemented.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
