Which of the following is an attack vector that can cause extensive physical damage to a datacenter
without physical access?

A.
CCTV system access

B.
Dial-up access

C.
Changing environmental controls

D.
Ping of death

Explanation:
Environmental systems include heating, air conditioning, humidity control, fire suppression, and power
systems. All of these functions are critical to a well-designed physical plant. A computer room will
typically require full-time environmental control. Changing any of these controls (when it was set to its
optimum values) will result in damage.
Incorrect Answers:
A: Closed Circuit TV (CCTV) surveillance can help lessen the success of unauthorized access attempts. This
is an access control which prevents physical access to a data center. In this case the attack vendor should
be one that can do damage without physical access.
B: Dial-up access when unauthorized may result in technical damage and not physical damage.
D: Ping of Death is a Denial of Service attack and involves technical controls and not an attack that results
in physical damages.
