Which of the following presents the STRONGEST access control?
A.
MAC
B.
TACACS
C.
DAC
D.
RBAC
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.Dulaney, Emmett and Chuck Eastton, CompTIA Security+ Study Guide, Sixth Edition, Sybex, Indianapolis, 2014, pp 146, 150
