Paper Summary:

This paper discusses the secure shell (SSH) protocol. It provides a brief overview of the secure shell protocol including its origin and why it was developed and the current state of the secure shell protocol. It then focuses on the secure shell protocol itself which consists of the transport, user authentication, connection protocols and the secure shell packet configuration. A discussion of the client and server costs of secure shell including the availability of the open version of secure shell (OpenSSH) follows, with a comparison of the differences between the commercial and free versions available for downloading. It ends with a discussion of the usage of secure shell and a working practical example of how secure shell clients and servers interact with one another.

From the Paper:

"The traditional insecure methods of connecting to networks using telnet, remote shell (RSH), or file transfer protocol (FTP), transfer commands and passwords in clear text, making them vulnerable to security attacks. These insecure protocols may now be replaced by using the SSH protocol which encrypts the clear text into an unreadable format which eliminates the risk of the message being read if captured in transmission."
