Monitor the Central Access Policies Associated with Files and Folders

Updated: July 3, 2013

Applies To: Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2



This topic for the IT professional describes how to monitor changes to the central access policies that are associated with files and folders when you are using Advanced Security Auditing options to monitor dynamic access control objects.

This security audit policy and the event that it records are generated when the central access policy that is associated with a file or folder is changed. This security audit policy is useful when an administrator wants to monitor potential changes on some, but not all, files and folders on a file server.

For information about monitoring potential central access policy changes for an entire file server, see Monitor the Central Access Policies that Apply on a File Server.

noteNote
The contents of this topic apply to the list of supported Windows operating systems designated in the Applies To list at the beginning of this topic.

Use the following procedures to configure settings to monitor central access policies that are associated with files. These procedures assume that you have configured and deployed Dynamic Access Control in your network. For more information about how to configure and deploy Dynamic Access Control, see Dynamic Access Control: Scenario Overview.

noteNote
Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings.

  1. Sign in to your domain controller by using domain administrator credentials.

  2. In Server Manager, point to Tools, and then click Group Policy Management.

  3. In the console tree, right-click the flexible access Group Policy Object, and then click Edit.

  4. Double-click Computer Configuration, double-click Security Settings, double-click Advanced Audit Policy Configuration, double-click Policy Change, and then double-click Audit Authorization Policy Change.

  5. Select the Configure the following audit events check box, select the Success check box (and the Failure check box, if desired), and then click OK.

  6. Enable auditing for a file or folder as described in the following procedure.

  1. Sign in as a member of the local administrators group on the computer that contains the files or folders that you want to audit.

  2. Right-click the file or folder, click Properties, and then click the Security tab.

  3. Click Advanced, and then click the Auditing tab.

    If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.

  4. Click Add, type a user name or group name in the format contoso\user1, and then click OK.

  5. In the Auditing Entries for dialog box, select the permissions that you want to audit, such as Full Control or Delete.

  6. Click OK four times to complete the configuration of the object SACL.

  7. Open a File Explorer window and select or create a file or folder to audit.

  8. Open an elevated command prompt, and run the following command:

    gpupdate /force

After you configure settings to monitor changes to the central access policies that are associated with files and folders, verify that the changes are being monitored.

  1. Sign in as a member of the local administrators group on the computer that contains the files or folders that you want to audit.

  2. Open a File Explorer window and select the file or folder that you configured for auditing in the previous procedure.

  3. Right-click the file or folder, click Properties, click the Security tab, and then click Advanced.

  4. Click the Central Policy tab, click Change, and select a different central access policy (if one is available) or select No Central Access Policy, and then click OK twice.

    noteNote
    You must select a setting that is different than your original setting to generate the audit event.

  5. In Server Manager, click Tools, and then click Event Viewer.

  6. Expand Windows Logs, and then click Security.

  7. Look for event 4913, which is generated when the central access policy that is associated with a file or folder is changed. This event includes the security identifiers (SIDs) of the old and new central access policies.
