The following syntax shows how to use icacls with a file object: icacls :] ] ] ] ] Later in this guide, we will see how to use icacls to view and modify the ILs. The terms MAC, WIC, WIL, IL, MIL, etc., used throughout this guide, essentially mean the same thing. The icacls command is primarily used to manage DACLs in Windows, but it can also be used to manage ILs with certain limitations. The following screenshot shows that most core Windows processes are running with System integrity, the user processes are running with Medium integrity, and the processes launched with elevated tokens (e.g., powershell and procexp64) are running with High integrity.ĭisplaying the IL of processes using Process Explorer 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.
