Discussion

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

Check Content

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.

For server core installations, run the following command:

Secedit /Export /Areas SecurityPolicy /CFG C:\Path\FileName.Txt

If "LSAAnonymousNameLookup" equals "1" in the file, this is a finding.

Fix Text

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Network access: Allow anonymous SID/Name translation" to "Disabled".
