Title

Windows Server 2022 administrator accounts must not be enumerated during elevation.

Control

If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\CredUI\ Value Name: EnumerateAdministrators Type: REG_DWORD Value: 0x00000000 (0)

Discussion

Enumeration of administrator accounts when elevating can provide part of the logon information to an unauthorized user. This setting configures the system to always require users to type in a username and password to elevate a running application.
