ABSTRACT:
A first plurality of operating system processes is assigned to a first protection domain, and a second plurality of operating system processes is assigned to a second protection domain. One or more hardware protection mechanisms are used to prevent the first plurality of operating system processes from accessing the memory space of the second plurality of operating system processes, and also to prevent the second plurality of operating system processes from accessing the memory space of the first plurality of operating system processes.
