When the WDigest Authentication protocol is enabled, plain-text passwords are stored in the Local Security Authority Subsystem Service (LSASS), exposing them to theft. WDigest is disabled by default in Windows Server 2019. This setting ensures this is enforced.

Fix Text (F-5952r354980_fix)

Configure the policy value for Computer Configuration >> Administrative Templates >> MS Security Guide >> "WDigest Authentication (disabling may require KB2871997)" to "Disabled". This policy setting requires the installation of the SecGuide custom templates included with the STIG package. "SecGuide.admx" and " SecGuide.adml" must be copied to the \Windows\PolicyDefinitions and \Windows\PolicyDefinitions\en-US directories respectively.
