Published: August 19, 2009

Applies To: Windows 7, Windows 8, Windows 8.1, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2



This planning topic describes what you need to investigate, determine, and record in your application control policies plan when you use AppLocker.

To complete this AppLocker planning document, you should first complete the following steps:

  1. Determine Your Application Control Objectives

  2. Create List of Applications Deployed to Each Business Group

  3. Select Types of Rules to Create

  4. Determine Group Policy Structure and Rule Enforcement

After you determine how to structure your Group Policy Objects (GPOs) so that you can apply AppLocker policies, you should record your findings. You can use the following table to determine how many GPOs to create (or edit) and which objects they are linked to. If you decided to create custom rules to allow system files to run, note the high-level rule configuration in the Use default rule or define new rule condition column.

The following table includes the sample data that was collected when you determined your enforcement settings and the GPO structure for your AppLocker policies.
