AppLocker calls the Application Identity component to calculate the file attributes. When a new DLL loads, a notification is sent to AppLocker to verify that the DLL is allowed to load.

It then updates the new process's token with these attributes and checks the AppLocker policy to verify that the executable file is allowed to run. When a new process is created, such as an executable file or a Universal Windows app is run, AppLocker invokes the Application Identity component to calculate the attributes of the main executable file used to create a new process. AppLocker policies are conditional access control entries (ACEs), and policies are evaluated by using the attribute-based access control SeAccessCheckWithSecurityAttributes or AuthzAccessCheck functions.ĪppLocker provides three ways to intercept and validate if a file is allowed to execute according to an AppLocker policy.
