Certified Information Systems Security Professional (CISSP) — Question 484

An organization wants to define as physical perimeter. What primary device should be used to accomplish this objective if the organization's perimeter MUST cost- efficiently deter casual trespassers?

Answer options

• A. Fences three to four feet high with a turnstile
• B. Fences six to seven feet high with a painted gate
• C. Fences accompanied by patrolling security guards
• D. Fences eight or more feet high with three strands of barbed wire

Correct answer: A

Explanation

The correct answer is A because fences that are three to four feet high with a turnstile provide a cost-effective solution to deter casual trespassers while still maintaining accessibility. Options B, C, and D are either more expensive or offer higher security that may not be necessary for casual trespassers, making them less suitable for this organization's specific requirement.
