Close the command window and restart the computer. Copy the command below, paste it into the command window and press ENTER:ģ. Run the Command Prompt as an administrator.Ģ. Restore Default Startup Configuration of Application Identityīefore you begin doing this, make sure that all the services on which Application Identity depends are configured by default and function properly. While Application Identity is stopped, the Smartlocker Filter Driver service cannot be launched. DependenciesĪpplication Identity cannot be started under any conditions, if the following services are disabled, deleted or working improperly: Then Windows 10 will start up and notify the user that the AppIDSvc service has failed to start due to the error. If Application Identity fails to start, the failure details are being recorded into Event Log. When the Application Identity service is started, it is running as NT Authority\LocalService in a shared process of svchost.exe along with other services. In Windows 10 it is starting only if the user, an application or another service starts it. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AppIDSvcĪpplication Identity is a Win32 service. %SystemRoot%\system32\svchost.exe -k LocalServiceNetworkRestricted -p Disabling this service will prevent AppLocker from being enforced. Remove-JCCommandTarget -CommandID $AppLockerCommandID -SystemID $agentconf.Application Identity (AppIDSvc) Service Defaults in Windows 10ĭetermines and verifies the identity of an application. # Remove the hardened device from the Command itself # Execute the Command to harden the device # Apply AppLocker via JumpCloud CommandĪdd-JCCommandTarget -CommandID $AppLockerCommandID -SystemID $agentconf.systemKey It's the same approach: We will add a t rigger to the JumpCloud Command and make it consumable within the PowerShell Module. Just like in my previous article about Windows Hardening, you can apply this policy during the deployment before issuing the device to a user. In our example here, we will deny the execution of MS Teams ( because I prefer Slack) and MS Paint. Stop there and in a next step you can simply cleanup the XML-file by removing unnecessary lines ( "NotConfigured") which would lead to a failed application of the rules. You can follow the instructions in the article until " Creating the Policy". Generating the XML FileĪs this is well documented here, I won't repeat the whole content. Simplify creating and managing AppLocker rules by using Windows PowerShell.įirst you will need to create your Package App Rule (as an example) to come up with an XML-file containing the restrictions which we will apply later via a JumpCloud Commands using PowerShell and carrying the XML as an additional payload.Create rules on a staging server, test them, then export them to your production environment and import them into a Group Policy Object.Use audit-only mode to deploy the policy and understand its impact before enforcing it.For example, you can create a rule that allows all users to run all Windows binaries, except the Registry Editor (regedit.exe). Assign a rule to a security group or an individual user.You can also create rules based on the file path and hash. Define rules based on file attributes that persist across app updates, such as the publisher name (derived from the digital signature), product name, file name, and file version.
