Title

Anonymous SID/Name translation is allowed. (Cat I impact)

Discussion

This is a Category 1 finding because this setting controls the ability of users or process that have authenticated as anonymous users to perform SID/Name translation. This setting should be disabled, as only authorized users should be able to perform such translations.

Check Content

Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “Network access: Allow anonymous SID/Name translation” is not set to “Disabled”, then this is a finding. Documentable Explanation: The default setting for domain controllers is Enabled. Disabling it means that legacy systems may be unable to communicate with Windows Server 2003/2008 – based domains. This requirement should be documented with the IAO.

Fix Text

Configure the system to disable anonymous SID/Name translation.
