K12-Basic Sniffing Game

A sniffer is an application that can capture network packets. If the network packets are not encrypted, the data within the network packet can be read using a sniffer. Sniffing refers to the process used by attackers to capture network traffic using a sniffer. Once the packet is captured using a sniffer, the contents of packets can be analyzed. Telnet is a reliable connection-oriented Transmission control protocol but vulnerable too. It transmits information on clear text format and a sniffer can tap or simply use a sniffing application to theft the information over a TCP/IP network.
