CompTIA Security+ (SY0-501) — Question 347

A bank uses a wireless network to transmit credit card purchases to a billing system.
Which of the following would be MOST appropriate to protect credit card information from being accessed by unauthorized individuals outside of the premises?

Answer options

Correct answer: C

Explanation

A Faraday cage is designed to block electromagnetic fields, effectively preventing unauthorized wireless access to the data being transmitted. The other options do not provide the same level of protection against external wireless threats; an air gap is not applicable to wireless networks, infrared detection does not prevent access, and protected distributions are not specifically designed for wireless transmission security.
