  • Article

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

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

Record your findings

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

  1. Determining Your Application Control Objectives

  2. Creating the List of Applications Deployed to Each Business Group

  3. Selecting the Types of Rules to Create

  4. Determining Group Policy Structure and Rule Enforcement

After determining 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 contains the added sample data that was collected when determining enforcement settings and GPO structure for AppLocker policies.
