Enforcing minimum privileges for general system users can be easily achieved through the use of:

A.
TSTEC

B.
RBAC

C.
TBAC

D.
IPSEC

Explanation:
Ensuring least privilege requires identifying what the user’s job is, determining the minimum set of
privileges required to perform that job, and restricting the user to a domain with those privileges
and nothing more. By denying to subjects transactions that are not necessary for the performance of
their duties, those denied privileges couldn’t be used to circumvent the organizational security

policy. Although the concept of least privilege currently exists within the context of the TCSEC,
requirements restrict those privileges of the system administrator. Through the use of RBAC,
enforced minimum privileges for general system users can be easily achieved.
