Wireless networking is highly susceptible to eavesdropping due to the nature of how data is transmitted. In wireless networks, data is sent over radio waves, which can be intercepted by anyone within the range of the signal. This means that without proper security measures, attackers can potentially listen in on communications, capture sensitive information, or even gain unauthorized access to the network.

To mitigate these risks, it is essential to implement strong security protocols, such as WPA3 (Wi-Fi Protected Access 3), which offers advanced encryption that helps protect data as it travels through the air. Other security practices include using strong, unique passwords, enabling network encryption, and regularly updating firmware to patch vulnerabilities. In contrast, wired networks typically use cables for transmission, making it much more difficult for unauthorized individuals to intercept data without physical access to the network infrastructure. This fundamental difference in how data is transmitted is key to understanding the security implications associated with each type of networking.
