C: The Kernel At the core of the OS is the Kernel. At ring 0 (or 3), it interfaces between the operating system (and applications) and the hardware. Microkernels are modular kernels. The reference monitor is a core function of the kernel; it handles all access between subjects and objects. It is always on and can’t be bypassed.
