An AppLocker is system software that is only supported in Windows Server and Windows 10 for now. It applies in whitelisting executable files, Windows installer, Dynamic link libraries, scripts, apps and package app installers. An AppLocker is helpful when you need to define rules for file attributes during app updates, and you have to put product name, file name, and publisher name.
Moreover, it also helps in creating a security rule for a group of individuals in the same organization. You can use it to mark exceptions to certain rules, deploy policies by applying audit-only rules by running binaries and creating and managing rules in Windows PowerShell. Furthermore, using an AppLocker, you can create rules for a server, test them, and add them to the Group Policy Object.
Advantages Of Windows AppLocker
Using Windows AppLocker to keep your company’s data safe and create a security wall is a great benefit. You also get the following perks for using it:
- Helps in reducing administrative overhead costs by cutting down the number of help desks in your company. This is a requirement when many users need to run applications that they are not authorized to.
- In the event log, AppLocker helps to add its policies in an audit-only manner that you can later access through Windows PowerShell.
- The AppLocker uses its security feature to keep apps from running on the system if they are not authorized. In most cases, they get blocked, which means absolutely no chance of malware or viruses harming your computer.
- AppLocker makes it easy to identify authorized users while accessing licensed and unlicensed software.
- It promotes more uniformity in app deployment within business groups by allowing only supported apps to run.
- Organizations have found the AppLocker to be of great value in place of Software Restriction Policies.

- Once again go to Computer Settings and then Policy.
2. Furthermore, go to Windows Settings, followed by Security Settings and System Services.
3. Under System Services, click on Application Identity and check on Automatic. With these steps, the app will be able to set up your AppLocker to Basic Settings.
Moreover, it would help if you remembered a few things. Firstly, only the person who has chosen the Audit can review logs. They can view it in Windows event viewer, further available under the Application and Services Log. Go to Microsoft, followed by Windows and then to AppLocker.
Furthermore, it would be best to note that only files located under c:\program files, C:\program files (x86) and C:\Windows will run under the AppLock. Thus, an AppLocker, assures you that no malware or virus will be able to reach these files.
AppLocker is an essential tool these days for those organizations who value their information and confidential data above all. Moreover, one must remember that when you run a process, it comes in the same level of access as the user. And as a result, the data or app is vulnerable to getting deleted or transmitted outside the organization. It can also happen if a user unknowingly runs malware or suspicious files on their system. Therefore, an AppLocker is handy as it stops running these applications without the authorizer’s permission.
