The security concept of “separation of duties” is most similar to the operation of which type of security device?

A.
Firewall

B.
Bastion host

C.
Intrusion Detection System

D.
Honeypot

Explanation:
In most enterprises the engineer making a firewall change is also the one reviewing the firewall metrics for
unauthorized changes. What if the firewall administrator wanted to hide something? How would anyone ever
find out? This is where the separation of duties comes in to focus on the responsibilities of tasks within security.
