A.
Procedural Controls

B.
Hardware Devices

C.
Electronic Systems

D.
Security Guards

Explanation:
One drawback of security guards is that the cost of maintaining a guard function either internally or through an
external service is expensive.
With common physical security risk countermeasures such as door entry control systems or perimeter fencing,
there is typically a one-off cost when the countermeasure is implemented. With security guards, you have the
ongoing cost of paying the salary of the security guard.
Incorrect Answers:
A: Procedural controls consist of approved written policies, procedures, standards and guidelines. The cost of
implement procedural controls is not more costly than the ongoing costs associated with security guards.
Therefore, this answer is incorrect.
B: Hardware Devices typically have a one-off cost when they are implemented and they may have a small cost
for maintenance. However, this cost not more costly than the ongoing costs associated with security guards.
Therefore, this answer is incorrect.
C: Electronic Systems typically have a one-off cost when they are implemented and they may have a small cost
for maintenance. However, this cost not more than the ongoing costs associated with security guards.
Therefore, this answer is incorrect.
