Introduction

App Locker is a powerful feature built into Windows that allows users to whitelist applications, giving them control over which programs can be run on their machines. In this article, we will provide an overview of what App Locker is and how it works. We will also discuss how to set up App Locker in both Windows 10 Enterprise and Windows 10 Professional, and explore its potential in protecting against malware. So, let's dive in and learn more about this useful Windows security feature.

📌 What is Windows App Locker?

App Locker is a facility built into Windows that allows users to control which applications can be executed on their systems. Using App Locker, administrators can create policies to approve or deny the running of specific applications based on various criteria, such as file path, publisher, or hash value. By whitelisting trusted applications and blocking unauthorized or potentially harmful ones, App Locker helps enhance the security of Windows systems.

📌 How Does App Locker Work?

App Locker relies on a combination of Group Policy settings and the Application Identity service to enforce application control policies. The policies can be based on file attributes, such as path, file name, publisher, or digital signature. When an application is launched, the Application Identity service checks whether it matches any of the allowed rules defined in the policies. If there is a match, the application is allowed to run. If not, it is blocked from executing.

📌 App Locker in Windows 10 Enterprise

To utilize App Locker in standalone mode, the machine needs to be running Windows 10 Enterprise. However, it is also possible to use App Locker with Windows 10 Professional by deploying the policies through a management tool like Intune. In this example, we will focus on the standalone version of App Locker.

📌 App Locker in Windows 10 Professional

For organizations using Windows 10 Professional, App Locker can be deployed by integrating it with Microsoft Intune. This allows administrators to centrally manage and enforce application control policies across multiple devices. While the setup process may be slightly different from the standalone version, the functionality and benefits of App Locker remain the same.

📌 Setting Up App Locker in Windows 10

To set up App Locker in Windows 10, you need to ensure that the Application Identity service is running. This service is responsible for enforcing the application control policies. You can check the status of the service by going to the Services area and locating the "Application Identity" service. If it is not running, you can start it manually.

📌 Running App Locker in Standalone Mode

Once the Application Identity service is running, you can configure App Locker through the Local Security Policy settings. To access these settings, search for "secpol" and select the "Local Security Policy" option. From there, navigate to "Application Control Policies" and find the App Locker section. Verify that the properties are configured and set to enforce.

📌 Customizing App Locker Policies

Within App Locker, you can create rules to allow or deny the execution of specific applications based on various attributes. By right-clicking on the App Locker folder, you can create new rules and specify the conditions for allowing or blocking applications. It is important to have the default allow rules in place before creating any deny rules to ensure the desired behavior.

📌 The Power of App Locker in Protecting Against Malware

One of the primary use cases for App Locker is protecting against malware. By restricting the execution of applications to trusted locations, such as program files and the Windows directory, you can prevent users from running potentially harmful files. This can help mitigate the risk of ransomware and other types of malware infecting your system.

📌 Conclusion

App Locker is a valuable security feature in Windows that provides administrators with granular control over which applications can be run on their machines. Whether you are using Windows 10 Enterprise or Professional, App Locker offers a powerful toolset for enhancing the security of your systems. By following the steps outlined in this article, you can easily set up and customize App Locker to meet your specific requirements and protect against possible security threats.
