Active Directory Database Protection wizard

The Active Directory Database Protection wizard opens when you click Add or Edit on the Active Directory Database Protection page. Using this wizard you can define the Active Directory Database processes to protect from unauthorized modifications.

* 
NOTE: You can also open the protection wizard from the event details pane. Simply open the Search Results tab, select an event, and click the Protect Object button.
The following table provides a description of the available fields and controls:
Table 10. Active Directory Database Protection wizard
Select Active Directory Database processes to protect: On the first page of the wizard, enter a name for the template and select the Active Directory database processes that are exempt from protection.

Template Name

Enter a descriptive name for the protection template.

(Optional) Select processes exempt from protection: Select processes to exclude from protection (for example, changes made by the processes specified on this page will be excluded from protection).

Add

Select one or more processes from the process list and click Add to move these processes to the exclusion list. By default, all processes (except lsass.exe) will be audited.

You can also view processes on a different server or enter a process not listed in the process list.

Remove

The list box across the bottom of the page displays the objects that are exempt from auditing. Click Remove to remove a process from the exemption list.

Setting extra security on protected objects

* 
NOTE: The Security feature is only available if you have selected to save your Active Directory and Group Policy protection templates in Active Directory instead of SQL (using the Protection tab in the Coordinator Configuration tool). See the Change Auditor User Guide or online help for more information about the Coordinator Configuration tool.

By default, Change Auditor settings are accessible by all domain administrators. In some environments, there are many individuals assigned domain administrator privileges. You can use the Security feature to provide an extra layer of security for your protected objects. You can delegate the right to manage protected objects to trusted administrators, limiting the number of administrators that can change settings.

When you change the security settings on a protected object through the Active Directory Protection page (or Group Policy Protection page) in Change Auditor, you are not changing the permissions assigned to the object. You are changing the access rights on who can change the Change Auditor settings.

If you do not want to use the default global catalog to apply the ACLs to the protected object, click Connect To and enter the domain controller to use.

To set extra security on a protection template:
1
On the Active Directory Protection page (or Group Policy Protection page), right-click the protection template and click Security.
The Access Control editor is displayed for the selected object.
2
Select the permissions then click OK.
* 
NOTE: Selecting access rights is similar to selecting access rights in Active Directory Users and Computers.

Each entry for the objects listed in the Protection template has it's individual security settings.

To set individual settings:
1
On the Active Directory Protection page (or Group Policy Protection page), click the + icon next to the protection template.
2
Right-click the entry in the template that want to set the security on and select Security.
3
Select the permissions and click OK.
* 
NOTE: Selecting access rights is similar to selecting access rights in Active Directory Users and Computers.

For simple Active Directory attribute changes (such as Add Attribute, Modify Attribute, Delete Attribute), the Event Details pane features an option to restore changed values. When applicable, Restore Value is displayed at the top of the Event Details pane, allowing you to restore a changed value without needing to leave the client or use additional tools.

* 
NOTE: The Restore Value feature honors the logged on user’s domain rights. If the logged on user does not have sufficient rights to perform the restore, a dialog is displayed allowing the user to enter elevated credentials. If a user does not have sufficient privileges, Change Auditor displays a failure message noting either an access denial or a login failure.
