![]() If end users are to install arbitrary printer drivers on their own publisher rules need to be configured that allow the execution of programs from specific vendors.Besides the 6 best app locks mentioned above, you can also incorporate another app that will provide more than just locking apps. Most printer drivers are packaged as executables – whose execution is blocked by AppLocker, of course. That, however, is only part of the solution. The installation of printer drivers for users without administrative rights can be enabled easily by adding the GUID to the policy Computer Configuration\Policies\Administrative Templates\System\Driver Installation. Instead of allowing execution of anything from a specific path we can allow execution of anything from a specific vendor: configure a publisher rule that allows execution of all files digitally signed by the VPN client software vendor. ![]() The temp directories are located inside the user profiles and writeable by the user adding a path rule for temp is not exactly desirable from a security point of view. This works by downloading to and executing files from the user’s temp directory, which would be blocked by AppLocker without additional configuration. Software like the Aventail VPN client installs in user context from the web browser. Add a script path rule to allow execution of C:\Users\*\AppData\Local\Softgrid Client\*\*.bat VPN Client Software App-V SCRIPTBODY scripts are executed from batch files created on the fly and stored temporarily on the hard disk.Path rule to allow execution from the Q: drive for everyone (if App-V 4.x is used with App-V 5 this is not necessary any more).Path rule to allow execution from the \\domain\sysvol\domain\policies directory for everyone (to allow the execution of logon scripts).You can use the (AppLocker, not environment!) variable %PROGRAMFILES% which applies to both program directories on an 圆4 system ( C:\Program Files and C:\Program Files (x86)). Path rule to allow execution from the Program files directories for everyone.Path rule to allow execution from the Windows directory for everyone.Lockers at Keukenhof, Holland by Beyond Elements under CC More Recommended Rules General You can then add users to that group as necessary without even having to make them members of the local Administrators. Recommendation: add a path rule that allows execution for a special NoAppLocker domain group (use an asterisk (*) for the path). by right-clicking and selecting run as administrator from the context menu. If you want to run the application you need to run it elevated, e.g. The only thing you get when you double-click the executable is an error message. As an admin, execution should be allowed, right? Wrong. Here is a nice way to shoot yourself in the foot: block an application that requires elevation. ![]() ![]() Administrators wishing to bypass AppLocker need to start executables from an elevated command prompt (or right-click and select run as administrator), which is often impractical. With the Administrators‘ SID gone, AppLocker is active for administrators in the same way it is for all other users. Remember: UAC filters the SID for the group Administrators from the access token during normal operation. However, if UAC is enabled, that rule is not very useful. After all, someone needs to be able to troubleshoot and perform maintenance. One of the default rules allows unrestricted application execution for administrators. This article is part of my small series about AppLocker, a technology built into Windows that enables administrators to audit and optionally block application execution. ![]()
