Openssh - Secure Transfer Protocol

SSH, short for Secure Shell [1], is a security protocol built on top of the application and transport layers, providing a secure transfer and usage environment for a computer’s Shell. Using the SSH protocol can effectively prevent information leaks during remote management. OpenSSH (OpenBSD Secure Shell) [2] is an implementation that uses SSH to encrypt communication over a computer network. It’s the open source alternative that replaces the commercial version provided by SSH Communications Security. OpenSSH is currently a sub-project of OpenBSD.
