Eavesdropping usually is more of a concern for which type of LANs?

• A. Wired, wireless
• B. Wireless, wired
• C. About equal for wired and wireless
• D. None of the above

Answer: (B)

Eavesdropping is more of a concern for wireless LANs because radio signals travel through the air and can be intercepted by any device within range with suitable equipment. This makes passive listening easy for someone nearby, so protecting confidentiality relies heavily on strong wireless encryption and proper authentication. In wired LANs, traffic follows cables, and switches typically forward frames only to the destination port, meaning an attacker would need physical access to the network or to tamper with hardware to capture data. While eavesdropping can occur on wired networks, it requires more direct access and effort. For these reasons, wireless networks present a higher eavesdropping risk than wired ones.
