Explanation:
A protection domain consists of the execution and memory space assigned to each process. The purpose of
establishing a protection domain is to protect programs from all unauthorized modification or executional
interference. The security perimeter is the boundary that separates the Trusted Computing Base (TCB) from
the remainder of the system. Security labels are assigned to resources to denote a type of classification.
Abstraction is a way to protect resources in the fact that it involves viewing system components at a high level
and ignoring its specific details, thus performing information hiding.
