SSH (Secure Shell)

SSH (Secure Shell)

SSH is a protocol similar to telnet which also facilitates connection to remote hosts for communication. However, SSH has an upper hand over telnet in terms of security. Telnet was primarily designed to operate within the local network and hence does not take care of security. On the other hand SSH manages to offer total security while connecting to remote hosts on a remote network or Internet.

Akin to telnet SSH also uses a client software and requires a username and Password to establish connection with the remote host.
