Barry was reviewing his organization’s perimeter firewall ruleset and determined that it contains rules that allow unnecessary access. What type of control flaw has Barry discovered?

A. Corrective
B. Detective
C. Preventive
D. Deterrent

Correct Answer: C

Firewalls serve to block attempted access to the organization’s networks and systems. Therefore, they are best described as preventative controls. The purpose of a detective control is to identify attacks that are currently taken place or have taken place in the past. The purpose of a deterrent control is to discourage an attacker from attempting to undermine security. The purpose of a corrective control is to help the organization recover after a security incident.
