GIAC Security Essentials Certification (GSEC) — Question 29

Which of the following is TRUE regarding the ability of attackers to eavesdrop on wireless communications?

Answer options

• A. Eavesdropping attacks cannot be performed through concrete walls.
• B. Eavesdropping attacks can take place from miles away.
• C. Eavesdropping attacks are easily detected on wireless networks.
• D. Eavesdropping attacks require expensive devices.

Correct answer: B

Explanation

The correct answer is B because eavesdropping attacks can indeed be conducted from long distances, especially if the wireless signal is strong enough. Option A is incorrect as concrete walls can attenuate signals but do not completely block them. Option C is false since eavesdropping can often go undetected on wireless networks. Option D is misleading because while some specialized equipment can be expensive, many eavesdropping attacks can be conducted with relatively inexpensive devices.
