Introduction

Enabling Active Directory protection allows you to lock down critical objects and attributes to prevent accidental or unauthorized creations, modifications, or deletions. This allows you to protect the environment from harmful changes that could open security holes or cause resources to become unavailable. Once enabled, if an unauthorized user attempts to modify or delete a protected object, Change Auditor prevents the operation and captures an event.

Protection can be defined for any Active Directory, Group Policy, or ADAM (AD LDS) object that you consider critical such as Organizational Units, Group Policy Object, and service accounts.

 

Active Directory object protection

When configured, Change Auditor prevents changes from occurring to a protected object regardless of who attempts to change the object and the tool or method used. Attempts to change or delete a protected object fail and an event is generated. These ‘failed’ events are identified in the client by displaying ‘Protected’ in the Result column on the Search Results page and Result field in an event’s detail pane.

See the Change Auditor User Guide for more information about defining the events to be captured based on result.

Active Directory protection page

This page displays when you select Active Directory from the Protection task list in the navigation pane of the Administration Tasks tab. From here, you can start the Active Directory Protection wizard to define critical Active Directory 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 Active Directory protection page contains an expandable view of all previously defined Active Directory protection templates. To add new template, use the Add button.

Once added, the following information is provided for each template:

Indicates whether the template is enabled or disabled. To enable/disable the template, place your cursor in this Status cell, click the arrow control and select the appropriate option from the drop-down menu.
Excluded from Protection - indicates that you selected the Allow option to allow only the selected accounts to change the protected objects.
Included in Protection - indicates that you selected the Deny option to allow all accounts to change the protected objects except for those selected.

Click the expansion box to the left of the template name to expand this view and display the following details for each template:

For Protect Only and Protect Except, click the expansion box to the left of the field to display the individual attributes included in the protection template.

Active Directory protection templates

The Active Directory protection templates are global settings and apply to all agents.

NOTE:  
If you are planning to use multiple Active Directory Protection templates, see the Change Auditor Technical Insight Guide for more information about how multiple protection templates are evaluated.

By default, the scope of coverage is for This object only; however, you can change this by using the drop-down arrow in the Scope cell in the list box and selecting one of the other two options:
NOTE: Allow is selected by default indicating that the selected users or groups can change the protected objects. However, you can select the Deny option and select individual users or groups that are not allowed to change the protected objects. When using the Deny option, you are allowing all users and groups to change the protected objects except for those selected on this page.

On the next page of the wizard, you can schedule when to enforce the protection. You can either select to always run the protection or run only during specific times. To enable the protection only during specific times, select Protection is scheduled, and define when it should be enabled (hour blocks on a weekly basis). The times selected are the local agent time where the template is applied.
Protect access from all locations: Protection is always enabled regardless of the location.
Protect access only from select locations: Protection is only enabled for the specified locations.
Disable protection only for select locations: Protection is disabled for the selected locations. Enabled everywhere else.
Protect access from all unknown locations: All Active Directory requests from locations that cannot be determined by the Change Auditor agent will be protected.
