Houston, TX, United States, 2006/03/13 - Because there is no greater concern for network managers than to protect the security of the corporate data, SSH protocol is widely used to provide strong authentication and secure communications - ZephyrCorp.com.

PASSPORT terminal emulation software can now be configured using Secure Shell (SSH) to connect to Unix systems. Secure Shell is a protocol that is used to secure communication between the client and server. It is intended as a replacement for telnet, rlogin, rsh, rcp, and ftp.
The Internet is not a secure environment for transmitting data. Information sent from one computer to another over the Internet can be intercepted and used maliciously to harm the original owner, or worse, an entire user community. It is possible to use SSH to prevent this from happening. Any time you have to do the following remotely over the Internet: log on to a host, perform file transfer, issue a command, access network resources, you need to consider using Secure Shell protocol.
Benefits of running PASSPORT with SSH
Privacy of your data – This is encrypting data that passes over the network. This end-to-end encryption is based on random keys that are securely negotiated for that session and then destroyed when the session is over.
Integrity of communications – Integrity means assuring that data transmitted from one end of a network connection arrives unaltered on the other side. It uses cryptographic integrity checking, which verifies both that transmitted data hasn't been altered and that it truly comes from the other end of the connection.
Authentication – This means verifying someone's identity (proof of identity of senders and receivers). Every SSH connection involves two authentications: the client verifies the identity of the SSH server (server authentication), and the server verifies the identity of the user requesting access (user authentication).
Authorization - This is access control to accounts that occurs after authentication. SSH servers have various ways of restricting clients' actions once connecting to the server. Authorization can be done at server wide level, per account, or at each user's files.
The Secure Shell provided by PASSPORT is based on the PuTTY implementation of SSH for Win32. Both SSH1 and SSH2 version are supported. Configuring a PASSPORT SSH session can easily be done from the Communication Setup (based on PASSPORT PC TO HOST).
