![]() ![]() ![]() To view the IL of a process in Windows, you can use the Process Explorer tool from Sysinternals. Windows uses the concept of ILs to protect the core files and processes, so even if you've got full control on a core system file, you will still get an Access is denied error when you delete that file. Therefore, a process with a lower IL cannot write to an object with a higher IL, even if there are full NTFS permissions on that object. In a nutshell, you could say that MIC and IL are more restrictive defense mechanisms used by Windows that override the NTFS permissions (DACL) and evaluate the object's access before the DACL does. Trusted installer-The trusted installer IL denotes the highest level of trustworthiness.System-The system IL is allocated to the core operating system processes and services.High-The high IL is allocated to the processes running with an elevated security token (processes launched using the Run as Administrator option).The objects lacking an IL are by default treated as medium by Windows. This is the default and implicit IL in Windows. Medium-The processes started by standard and non-admin users are allocated an IL of medium by default.Such processes have very limited access to files and directories. Low-The processes that directly interact with the Internet are allocated a low IL by default.The processes that are anonymously logged on are automatically allocated an untrusted IL by Windows. ![]()
