Abstract :
Is virtualization the solution to computing security? A brief look at the history of computer security salvation might provide some insight. A basic concept underlying OS protection is separation. The OS provides separation of files, directories, processes, users, and devices from each other, even though the hardware lets them interact arbitrarily. In the OS´s role as mediator, it prevents user processes from subverting the OS and each other by limiting where they can read from and write to; dominating input, output, storage, and processing resources; and intermediating for the hardware mechanism so that only the OS has direct access.
