![]() Script rules apply to things like PowerShell scripts and batch files. The third type of AppLocker rules is a script rule.Windows Installer rules pertain to self-extracting executable packages, such as MSI files. The second type of AppLocker rules is a Windows Installer rule.Executable rules pertain to executable files, such as those with a. The first type of AppLocker rules listed within AppLocker is an executable rule.If you expand the Windows AppLocker container, shown in the figure above, the console will reveal four sub-containers, each of which are related to a specific type of rule. You can access Windows AppLocker through the PC’s local security policy. You can see what this looks like in Figure 1. Once the Local Group Policy Editor opens, navigate through the console tree to Computer Configuration \ Windows Settings \ Security Settings \ Application Control Policies \ AppLocker. Next, open the local security policy by entering the GPEdit.msc command at the Windows Run prompt. Once all of the applications have been installed, log into the PC using an account with local administrative privileges (assuming that you aren’t already logged in). If you happen to have a gold image that you use for operating system deployments, then it is a good idea to use that image to generate the reference OS. One important thing to keep in mind about the configuration process is that any apps that you install need to be of the same version, and reside in the same paths as they will on the production systems. Next, log into the device as an administrator and install all of the apps that you want to allow. To do so, you will need to install Windows 10 onto a physical or a virtual machine. With that said, the first step in the process is to create a reference device. To ease the creation of Windows AppLocker rules, Microsoft makes it possible to build a reference device and then create rules automatically based on that device’s configuration. Thankfully, there is a shortcut to the rule creation process. ![]() Even under the best of circumstances, this process requires a lot of trial and error. Setting up AppLocker usually means creating a complex set of rules for determining which applications are allowed to run. Although Windows AppLocker can be an effective tool for preventing the use of rogue software, it is notoriously difficult to properly configure. As such, AppLocker is best suited for small jobs rather than comprehensive application protection.AppLocker is a native Windows tool that can help organizations prevent users from running unauthorized applications on their PCs. It is difficult to create a comprehensive set of rules for AppLocker, and something as simple as a software patch can render certain types of rules ineffective. If on the other hand, your goal is to allow only certain applications to run, then you are probably be better off using a third-party tool. For example, if you want to phase out an application, you could create an AppLocker rule to prevent workers from using it. It is a good tool for blocking specific applications. For example, Executable Rules and Windows Installer Rules can identify an application based on its publisher, path or file hash.ĪppLocker works, but it is far from perfect. These rules use application attributes as a mechanism to identify applications. The rule types include Executable Rules, Windows Installer Rules, Script Rules and Packaged App Rules. There are four main types of AppLocker rules, and rules can be applied on a per-user or per-group basis. ![]() The Windows AppLocker settings exist within the Group Policy Object Editor at Computer Configuration > Windows Settings > Security Settings > Application Control Policies > AppLocker.ĪppLocker is based on a series of rules that either allow an application to run or prevent it from running.
