The main access threat to 802.11 wireless LANs is an attacker plugging into a wall jack. True or False?

• A. True
• B. False
• C. Sometimes true
• D. Not applicable

Answer: (B)

Access to an 802.11 wireless LAN happens through radio, so the primary risk is someone in range trying to connect or intercept traffic over the wireless link. A wall jack would only grant access to the wired side of the network, not directly to the wireless medium. If the wireless configuration is weak or open, or if rogue or misconfigured APs are present, an attacker can gain access or disrupt service without needing physical access to a wall socket. In practice, the biggest threats revolve around insecure authentication and encryption, rogue devices, and wireless-specific attacks (like deauthentication or traffic interception), rather than someone simply plugging into a wall jack. So the statement is false.
