SSH (Secure SHell) is a network protocol that covers authentication, encryption and the integrity of data transmitted over a network. Below is a quote from :
Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices. Used primarily on Linux and Unix based systems to access shell accounts, SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, leaving them open for interception. The encryption used by SSH provides confidentiality and integrity of data over an insecure network, such as the Internet.
SSH protocol has client/server architecture. An SSH server program accepts or rejects incoming connections. This article covers the most used SSH servers for Windows.
