Secure shell (SSH) can safely be called one of the rare successes in which a more secure technology has largely replaced a less secure but entrenched tool: telnet. We perform a market analysis to determine how and why SSH succeeded despite the existence of an entrenched legacy tool while similar technologies such as secure file transfer protocols have been far less successful. We show that network externalities, usually a first order effect, were not a significant factor impeding the adoption of SSH, and that SSH offered equivalent functionality and greater ease of use. We argue that these factors were the primary consideration in the willingness to change.

What is SSH SSH (Secure SHell) is a network protocol which provides a replacement for insecure remote login and command execution facilities, such as telnet, rlogin and rsh.

SSH also offers several additional useful features: Compression: traffic may be optionally compressed at the stream level. Public key authentication: optionally replacing password authentication. Authentication of the server: making man-in-the-middle attack more difficult Port forwarding: arbitrary TCP sessions can be forwarded over an SSH connection.
