Which method is suggested to mitigate wireless eavesdropping?

Using strong encryption and authentication at the lowest layer of the protocol is a highly effective method to mitigate wireless eavesdropping. In the context of wireless communications, sensitive data transmitted over the air can be susceptible to interception by unauthorized users. Strong encryption ensures that even if data packets are captured, they cannot be easily deciphered or manipulated by attackers.

Implementing robust authentication mechanisms adds an additional layer of security by ensuring that only authorized devices can connect to the wireless network. This dual approach of encryption and authentication makes it significantly more difficult for eavesdroppers to gain access to sensitive information. Protocols such as WPA3, which incorporate advanced encryption standards, exemplify this best practice, enhancing the security framework of wireless networks.

Other methods, such as avoiding encryption altogether or using outdated encryption protocols like WEP, greatly weaken security and expose the network to various threats. Increasing the coverage area of the wireless network does not inherently improve security and could potentially make the network more vulnerable by allowing eavesdroppers to access the network from a further distance.
