Enable Active Directory Auditing – A Step-by-Step Guide

Enable the Security Auditing

For security auditing, it is required to either modify default domain policy or create a new Group Policy Object and edit it. You have to, in fact, deal with Advanced Audit Policy Configuration for this. Perform the following steps for enabling the security auditing of Active Directory.

• • Go to Start Menu → Administrative Tools → Group Policy Management.
  • In the left pane, navigate to Forest → Domains → Domain Name. Expand it.
  • You can select either ‘Default Domain Policy’ or create a new Group Policy Object.
  • Right-click on ‘Default Domain Policy’ or other Group Policy Object.
  • Click ‘Edit’ in the context menu. It shows ‘Group Policy Management Editor’.
  • Go to Computer Configuration → Policies → Windows Settings → Security Settings → Advanced Audit Policy Configuration → Audit Policies.
    
    It lists all audit policies in the right pane.

    

    In order to configure all the policies, define the following categories and then configure them one after another

  • For example, click on the first policy – Account Logon and configure the audit events of its subcategories one after another.
  • Check Both Success and Failure

Enable the Global Object Access Auditing

Perform the steps below to audit the access of any object globally on the server.

• • Go to Start Menu → Administrative Tools → Group Policy Management.
  • In the left pane, navigate to ‘Forest → Domains → Domain Name. Expand it.
  • You can select either ‘Default Domain Policy’ or create a new Group Policy Object.
  • Right-click on ‘Default Domain Policy’ or another Group Policy Object.
  • Click ‘Edit’ in the context menu. It shows ‘Group Policy Management Editor’.
  • Go to Computer Configuration → Policies → Windows Settings → Security Settings → Advanced Audit Policy Configuration → Audit Policies. It lists all audit policies in the right pane.
  • Go to ‘Global Object Access Auditing’ node under ‘Audit Policies’ of advanced configuration.
  • Double click ‘Registry’ entry in the right details pane.
  • Check the box ‘Define this policy’. It enables the subsequent button.

• • Click ‘Configure’ to access the advanced Settings for Global Registry SACL’.

• • Click ‘Add’ to add users or groups of which access you want to audit. It shows ‘Auditing Entry for Global Registry SACL’ window.

• • Click ‘Select a Principal’ link. It shows ‘Select User, Computer, Service Account or Group’ dialog box on the screen.

• • Type the name of a user or group of which access you want to audit.
  • Click ‘Check Names’ button to validate the name.
  • Click ‘OK’. It takes you back to ‘Auditing Entry’ window.
  • Select ‘All’ in ‘Type’ drop-down menu.

• • Please make sure all 16 permissions are checked.
  • Click ‘OK’. It adds the rule to audit the selected user’s access to the registry and takes you back to ‘Advanced Security Settings’ window.

• Click ‘Apply’ and ‘OK’. It takes you back to event properties.
• Click ‘Apply’ and ‘OK’.
You can follow the similar above steps to configure ‘File System’ policy in ‘Global Object Access Auditing’.

Manage the Integrity of Advanced Auditing

The advanced auditing entries are often overwritten by the entries of basic auditing. Perform the following steps to configure that the advanced auditing entries will not be overwritten.

• Go to Start Menu → Administrative Tools → Group Policy Management.
• In the left pane, go to Forest → Domains → Domain Name. Expand it.
• You can select either ‘Default Domain Policy’ or create a new Group Policy Object.
• Right-click on ‘Default Domain Policy’ or another Group Policy Object.
• Click ‘Edit’ in the context menu. It shows ‘Group Policy Management Editor’.
• In the left tree pane, go to Computer Configuration → Policies → Windows Settings → Security Settings → Security Options.
• Double click ‘Audit: Force audit policy subcategory settings (Windows Vista or later) to override audit policy category settings’.
• Click ‘Define this policy setting’ and click ‘Enabled’.
• Click ‘Apply’ and ‘OK’.

Update Group Policy Object

Start the command prompt or ‘Run’ prompt as an Administrator and execute the following command.

• gpupdate /force
It applies the modified security auditing policies on the server. Alternatively, you can logoff and logon the Administrator.

Verify the Auditing Policies

It is the time to verify that the modified auditing policies have been applied or not. Run the following command on the Command Prompt.

• • auditpol.exe /get /category:*

It lists the status of all auditing policies (both basic and advanced) on the server. Please verify both ‘Success’ and ‘Failure’ events for the policies, which you have enabled.

Custom Views to Keep a Check

Once the security auditing of Active Directory has been enabled, you receive these events in the Security section under ‘Windows Logs’ in Event Viewer. You can customize the view to keep a check only on critical and error logs. Follow the steps below:

• • Right-click on Security to access the context menu.

• • Click ‘Create Custom View’ option. It shows the following dialog box.

• • Select ‘Critical’, ‘Error’, and ‘Warning’ to show only these types of logs in the new custom view. Keep ‘Security’ selected in ‘Event logs’.
  • Click ‘OK’. It shows the following box to save the created view.

• • You can provide a new name for this view.
  • It will be displayed the node ‘Custom Views’. You can also create a new folder to save this node by clicking ‘New Folder’.
  • A newly created custom view is displayed under ‘Custom Views’.

Right pane in this window shows a list of actions you can perform such as
• Import Custom View: It lets you import the custom view, which can be exported later on.
• Filter Current Custom View: Click it to customize the current view using the same dialog box, which you used to create it.
• Properties: Click it to change the name and description of this view.
• Find: Click it to search in the current view.
Other basic options let you rename, delete, or refresh the view.

Drawbacks of Native Auditing

After enabling the security auditing, you can browse the Event Viewer and view the captured events in the ‘Security’ logs. However, there are few drawbacks as listed herein below.

• No predefined audit reports for Security Auditing.
• More than one event is recorded for only one change.
• No specific or detail information which object was accessed or changed.
• No information about before- and after-values of a changed object.
