A company is trying to implement physical deterrent controls to improve the overall security posture of
their data center. Which of the following BEST meets their goal?

A.
Visitor logs

B.
Firewall

C.
Hardware locks

D.
Environmental monitoring

Explanation:
Hardware security involves applying physical security modifications to secure the system(s) and
preventing them from leaving the facility. Don’t spend all of your time worrying about intruders coming
through the network wire while overlooking the obvious need for physical security. Hardware security
involves the use of locks to prevent someone from picking up and carrying out your equipment.
Incorrect Answers:
A: Visitor logs will only allow you to check access to the premises and not safeguard against those visitors
that may carry equipment off the premises.
B: A firewall will only safeguard your network from intruders over the network/wired or wireless.
D: Environmental monitoring concerns safeguarding against events such as ware and flood damage,
temperature and humidity control, fire warnings, etc.
