A group of processes that share access to the same resources is called:

A.
A Trusted Computing Base (TCB)

B.
A protection domain

C.
An access control triple

D.
An access control list

Explanation:
In answer a, an access control list (ACL) is a list denoting which users have what privileges to a
particular resource. Table illustrates an ACL. The table shows the subjects or users that have access
to the object, FILE X and what privileges they have with respect to that file. For answer “An access
control triple”, an access control triple consists of the user, program, and file with the corresponding
access privileges noted for each user. The TCB, of answer “A Trusted Computing Base (TCB”, is
defined in the answers as the total combination of protection mechanisms within a computer
system. These mechanisms include the firmware, hardware, and software that enforce the system
security policy.
