Kernels and Privilege Levels An operating system's user mode (a privilege level) offers access to privileged commands, which are reserved for the kernel components of the operating system. Ring 0 of the onion model of the layered approach to operating system structuring is the innermost ring and corresponds to the kernel mode. The traditional UNIX kernel is an example of a microkernel.
