SSH

Secure Shell (SSH) is a network protocol that allows the user to securely access a computer over an unsecured network by providing a strong password and public key authentication. SSH uses a client-server model and usually listens on the Transmission Control Protocol (TCP) port 22. You can learn more about SSH here.
