Trusted Security Filter - TSF 101
TSF101 is a filter between a secure and a non-secure IP network. The main purpose of the TSF101 is to filter a defined set of messages from the secure network to the non-secure network in a specific environment. Messages that do not comply with the specification of the filter are rejected.
The TSF 101 hardware provides connection for audio devices, loudspeaker and lamps, and the Ethernet interfaces, but is used purely as a data filter between two IP based networks. In this configuration only the Ethernet interfaces and the alarm lamps and indicator lamps are used. All other interfaces are disabled.
The TSF 101 software performs the following main functions: Routing, Firewall and Red/Black separation.
