The Protocol IEC-608-5-104 has been used as a standard for connecting telecontrol systems, which are mostly not protected against attacks by a third party. Safeguarding these unprotected systems can partly result in expensive workarounds. For this reason, the IEC104 Security Proxy has been designed to provide a secure and reasonably priced alternative.
The IEC104 Security acts as an independent unit between control system and IEC104 end devices. It sets up connections to the end devices as an IEC104 master and serves as an IEC-104 slave towards the control system. This mechanism prevents direct connections between control system and end devices. Thereby, the IEC104 Security Proxy also supports IEC104-conpliant, redundant connections to control systems and RTU´s.
The additionally implemented monitoring and filtering functions extend the IEC104 Proxy application area.
A command line interface and a web interface will be used for the configuration of the IEC104 Security Proxy.
The high-performance hardware provides sufficient capacities for reliable communication-intensive process connections and high connection density. The robust, fanless device has an extended operating temperature range and, therefore, can be installed in harsh industrial environment.
By using the 19” Installation kit, the IEC104 Security Proxy can be inserted into 19” racks. Besides, the Installation kit enables the redundant power supply of the device.
