SSH is an abbreviation of Secure Shell, which is a program allowing secure remote login and secure network
services over an insecure network. It allows a secure login to remote host computers, a safe method of
executing commands on a remote end node, and will provide secure encrypted and authenticated
communication between two non-trusted hosts. SSH, with its array of unmatched security features is an
essential tool in today’s networking environment. It is a powerful guardian against numerous existing security
hazards that now threaten network communications.
