Telnet is a member of the TCP/IP family of protocols, and it allows a user to establish a remote session on a server. The protocol supports only alphanumeric terminals -- that is, it does not support mice and other pointing devices, nor does it support graphical user interfaces. Instead, all commands must be entered at the command line.
The Telnet protocol provides very little security. In a Telnet session that does not use NTLM authentication, all data, including passwords, is transmitted between client and server in plaintext. Because Telnet session traffic is not secure, you need to ensure that no sensitive data is sent during a Telnet session.
