Deploy Security Auditing with Central Audit Policies (Demonstration Steps)
Applies To: Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
In this scenario, you will audit access to files in the Finance Documents folder by using the Finance Policy that you created in Deploy a Central Access Policy (Demonstration Steps). If a user who is not authorized to access the folder attempts to access it, the activity is captured in the event viewer.
The following steps are required to test this scenario.
|Configure Global Object Access||In this step, you configure the global object access policy on the domain controller.|
|Update Group Policy Settings||Sign in to the file server and apply the Group Policy update.|
|Verify that the global object access policy has been applied||View the relevant events in the event viewer. The events should include metadata for the country and document type.|
In this step, you configure the global object access policy in the domain controller.
To configure a global object access policy
Sign in to the domain controller DC1 as contoso\administrator with the password pass@word1.
In Server Manager, point to Tools, and then click Group Policy Management.
In the console tree, double-click Domains, double-click contoso.com, click Contoso, and then double-click File Servers.
Right-click FlexibleAccessGPO, and click Edit.
Double-click Computer Configuration, double-click Policies, and then double-click Windows Settings.
Double-click Security Settings, double-click Advanced Audit Policy Configuration, and then double-click Audit Policies.
Double-click Object Access, and then double-click Audit File System.
Select the Configure the following events check box, select the Success and Failure check boxes, and then click OK.
In the navigation pane, double-click Global Object Access Auditing, and then double-click File system.
Select the Define this policy setting check box, and click Configure.
In the Advanced Security Settings for Global File SACL box, click Add, then click Select a principal, type Everyone, and then click OK.
In the Auditing Entry for Global File SACL box, select Full control in the Permissions box.
In the Add a condition: section, click Add a condition and in the drop-down lists select
[Resource] [Department] [Any of] [Value] [Finance].
Click OK three times to complete the configuration of the global object access audit policy setting.
In the navigation pane, click Object Access, and in the results pane, double-click Audit Handle Manipulation. Click Configure the following audit events, Success, and Failure, click OK, and then close the flexible access GPO.
In this step, you update the Group Policy settings after you have created the audit policy.
To update Group Policy settings
Sign in to the file server, FILE1 as contoso\Administrator, with the password pass@word1.
Press the Windows key+R, then type cmd to open a Command Prompt window.
If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
Type gpupdate /force and then press ENTER.
After the Group Policy settings have been applied, you can verify that the audit policy settings were applied correctly.
To verify that the global object access policy has been applied
Sign in to client computer, CLIENT1 as Contoso\MReid. Browse to the folder HYPERLINK "file:///\\\\ID_AD_FILE1\\Finance" \\ FILE1\Finance Documents, and modify Word Document 2.
Sign in to the file server, FILE1 as contoso\administrator. Open Event Viewer, browse to Windows Logs, select Security, and confirm that your activities resulted in audit events 4656 and 4663 (even though you did not set explicit auditing SACLs on the files or folders that you created, modified, and deleted).
A new logon event is generated on the computer where the resource is located, on behalf of the user for whom effective access is being checked. When analyzing security audit logs for user sign-in activity, to differentiate between logon events that are generated because of effective access and those generated because of an interactive network user sign in, the Impersonation Level information is included. When the logon event is generated because of effective access, the Impersonation Level will be Identity. A network interactive user sign in typically generates a logon event with the Impersonation Level = Impersonation or Delegation.
