Change Auditor for Active Directory 7.0.4 - User Guide

Group Policy Object protection

You can prevent all changes to Group Policy Objects, regardless of the tool that is used to make the change. Protection includes both portions of the Group Policy data: the Group Policy Object (GPO) in Active Directory and the actual configuration data stored in the SYSVOL share on domain controllers.

Group Policy protection page

The Group Policy protection page displays when you select Group Policy from the Protection task list in the navigation pane of the Administration Tasks tab. From here, you can start the Group Policy Protection wizard to define critical group policy objects to protect from unauthorized modifications. You can also edit existing templates, disable and enable templates, and remove templates that are no longer being used.

The Group Policy Protection page contains an expandable view of all previously defined Group Policy Protection templates. To add a Group Policy container to the protection list, use the Add button. Once added, the following information is provided for each template:
