Administer AppLocker

This article for IT professionals provides links to specific procedures to use when administering AppLocker policies.

AppLocker helps administrators control how users can access and use files, such as executable files, packaged apps, scripts, Windows Installer files, and DLLs. Using AppLocker, you can:

  • Define rules based on file attributes derived from the digital signature, including the publisher, product name, file name, and file version. For example, you can create rules based on the publisher attribute that is persistent through updates, or you can create rules for a specific version of a file.
  • Assign a rule to a security group or an individual user.
  • Create exceptions to rules. For example, you can create a rule that allows all Windows processes to run, except Registry Editor (regedit.exe).
  • Use audit-only mode to deploy the policy and understand its effect before enforcing it.
  • Import and export rules. The import and export affects the entire policy. For example, if you export a policy, all of the rules from all of the rule collections are exported, including the enforcement settings for the rule collections. If you import a policy, the existing policy is overwritten.
  • Simplify creating and managing AppLocker rules by using AppLocker PowerShell cmdlets.

Using the MMC snap-ins to administer AppLocker

You can administer AppLocker policies using the Group Policy Management Console to create or edit a Group Policy Object (GPO). To create or edit an AppLocker policy on a local computer, use the Local Group Policy Editor snap-in or the Local Security Policy snap-in (secpol.msc).

Administer AppLocker using Group Policy

You must have Edit Setting permission to edit a GPO. By default, members of the Domain Admins group, the Enterprise Admins group, and the Group Policy Creator Owners group have this permission. Also, the Group Policy Management feature must be installed on the computer.

  1. Open the Group Policy Management Console (GPMC).
  2. Locate the GPO that contains the AppLocker policy to modify, right-click the GPO, and then select Edit.
  3. In the console tree, double-click Application Control Policies, double-click AppLocker, and then select the rule collection that you want to create the rule for.

Administer AppLocker on the local PC

  1. Select Start, type local security policy, and then select Local Security Policy.
  2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then select Yes.
  3. In the console tree of the snap-in, double-click Application Control Policies, double-click AppLocker, and then select the rule collection that you want to create the rule for.
