34.7.2 SSH Overview
Unlike Telnet or FTP, which transmit data in clear text, SSH (Secure Shell) is a secure communication
protocol that combines authentication and data encryption to provide secure encrypted
communication between two hosts over an unsecured network.

34.7.2.1 How SSH Works
The following table summarizes how a secure connection is established between two remote hosts.
