Network sniffing is basically know to be the act of tapping into network traffics and modifying unsafe requests for both good and bad purposes.Network sniffing is also known as Packet Sniffing which means as its name implies; sniffing chunks of packets on a network. This kind of attack mostly arise when a user exposes their device to unsecured Wi-Fi networks.So using ethernet with softwares (Network monitoring softwares) I think would paly an important role in curbing such attacks.
