CompTIA Security Plus Mock Test Q894

Which of the following presents the STRONGEST access control?

A. MAC
B. TACACS
C. DAC
D. RBAC

Correct Answer: A
Section: Access Control and Identity Management

Explanation:
A: With Mandatory Access Control (MAC) all access is predefined. This makes it the strongest access control of the options presented in the question.

Incorrect Answers:
B: TACACS refers to a client-server-oriented environment similar to that of RADIUS and is in essence an authentication service. It is an older authentication protocol common to UNIX
networks that allows a remote access server to forward a user’s logon password to an authentication server to determine whether access can be allowed to a given system.
C: With Discretionary Access Control (DAC) access control incorporates some flexibility.
D: With Role-Based Access Control (RBAC) access control allows the user’s role to dictate access capabilities.
