[Reference: https://www.sciencedirect.com/topics/computer-science/network-sniffer, Transport layer encryption is the most effective way to protect against the use of a network sniffer, because it encrypts the data packets that are transmitted over a network, making them unreadable and useless for anyone who intercepts them. Transport layer encryption can be implemented using protocols such as Secure Sockets Layer (SSL), Transport Layer Security (TLS), or Secure Shell (SSH), which provide end-to-end encryption and authentication between the sender and the receiver of the data. By using transport layer encryption, the data can only be decrypted by the intended recipient, who has the proper key or certificate to do so. Therefore, even if a network sniffer captures the data packets, they cannot access or modify the sensitive information contained in them., References:, What is Packet Sniffing Attack in Network Sniffing?, EC-Council, Packet Sniffing Meaning, Methods, Examples and Best Practices, Spiceworks, What is a packet sniffing attack? + how to prevent it, Norton, ]
