CompTIA Security Plus Mock Test Q905

Which of the following security concepts can prevent a user from logging on from home during the weekends?

A. Time of day restrictions
B. Multifactor authentication
C. Implicit deny
D. Common access card

Correct Answer: A
Section: Access Control and Identity Management

Time of day restrictions limit when users can access specific systems based on the time of day or week. It can limit access to sensitive environments to normal business hours when
oversight and monitoring can be performed to prevent fraud, abuse, or intrusion.

Incorrect Answers:
B: Multifactor authentication requires a user to supply two or more authentication factors in order to prove their identity. This would not be restricted to weekends only.
C: Implicit deny says that if you aren’t explicitly granted access or privileges for a resource, you’re denied access by default. If this is true, time of the week will not be a factor.
D: Common Access Cards (CACs) are smart cards used by the U.S. government and military to physically access facilities.
