4.4.5 Secure Shell
Secure Shell or SSH is a set of standards and an associated network protocol that allows establishing a secure channel
between a local and a remote computer. It uses public-key cryptography to authenticate the remote computer and (optionally) to
allow the remote computer to authenticate the user. SSH provides confidentiality and integrity of data exchanged between the
two computers using encryption and message authentication codes (MACs). SSH is typically used to log into a remote machine
and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports connections; it can transfer files using the
associated SFTP or SCP protocols. An SSH server, by default, listens on the standard TCP port 22.
