What is SecureCATT?
SecureCATT is a software program that runs under the Windows operating system and acts as an encrypting "front end" to your Unisys MCP system. It is designed to accept incoming secure connections from the C.A.T.T. Terminal Emulator software. When configured for operation with SecureCATT, C.A.T.T. encrypts all messages going to the MCP host and sends them to the SecureCATT Server. SecureCATT decrypts the inbound messages and passes them along to your MCP system. SecureCATT then receives responses from the MCP system, encrypts them and sends them across the secure connection back to the C.A.T.T. Emulator where they are decrypted and displayed.
The SecureCATT software is parameter driven allowing you to establish secure channel definitions that fit your specific site. Each channel definition associates a given incoming TCP/IP server port number to a Telnet or CCF connection on a given Unisys MCP host platform. This architecture allows one copy of SecureCATT to front end multiple MCP platforms.
Each SecureCATT channel definition supports multiple incoming C.A.T.T. Emulator connections so, for a given MCP host, only one SecureCATT channel definition is required to support a large number of C.A.T.T. Emulator sessions.
