Allowing anonymous SID/Name translation can provide sensitive information for accessing a system. Only authorized users must be able to perform such translations.

Verify the effective setting in Local Group Policy Editor. Run "gpedit.msc".

Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options.

If the value for "Network access: Allow anonymous SID/Name translation" is not set to "Disabled", this is a finding.
