Title

Local users on domain-joined computers must not be enumerated.

Control

This requirement is applicable to domain-joined systems, for standalone systems this is NA. 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\Policies\Microsoft\Windows\System\ Value Name: EnumerateLocalUsers Value Type: REG_DWORD Value: 0

Discussion

The username is one part of logon credentials that could be used to gain access to a system. Preventing the enumeration of users limits this information to authorized personnel.
