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.
Mandates additional authentication for access under defined conditions, ensuring critical or high-risk functions are not left without authentication.
Identity providers mandate authentication for functions that would otherwise lack it.
Requires authentication for non-organizational users, preventing access to critical functions without proper identification and authentication.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
