The default ACL settings are adequate when the Security Option “Network access: Let everyone permissions apply to anonymous users” is set to “Disabled” (V-3377) and Power User Group Membership is restricted. If the default ACLs are maintained, the referenced option is set to “Disabled” and Powers Users are restricted, this check should normally be marked “Not a Finding” Note: Power Users is included in later Windows versions for backward compatibility. Note: If an ACL setting prevents a site’s applications from performing properly, the site can modify that specific setting. Settings should only be changed to the minimum necessary for the application to function. Each exception to the recommended settings should be documented and kept on file by the IAO. |
