SSH Protocols and Secure Shell Secure Shell is the secure login program that revolutionized remote management of networks hosts over the Internet. It is a powerful, very easy-to-use program that uses strong cryptography for protecting all transmitted confidential data, including passwords, binary files, and administrative commands. The benefits of SSH include: o Automatic authentication of users, no passwords sent in cleartext to prevent the stealing of passwords. o Multiple strong authentication methods that prevent such security threats as spoofing identity. o Authentication of both ends of connection, the server and the client are authenticated to prevent identity spoofing, trojan horses, etc. o Automatic authentication using agents to enable strong authentication to multiple systems with a single-sign-on. o Encryption and compression of data for security and speed. o Secure file transfer. o Tunneling and encryption of arbitrary connections.
