In this podcast recorded at IoT Solutions World Congress Barcelona 2016, Andrew Ginter, VP of Industrial Security at Waterfall Security, talks about Unidirectional Security Gateways. They can replace firewalls in industrial network environments, providing absolute protection to control systems and operations networks from attacks originating on external networks.
Unidirectional Gateway solutions come in pairs: the TX appliance contains a laser, and the RX appliance contains an optical receiver. The Gateway pair can transmit information out of an operations network, but is incapable of propagating any virus, DoS attack, human error or any information at all back into the protected network.
Waterfall agent software gathers data in real time from operations servers inside the protected network. The software transmits that data to the external network, and populates replica servers with the data.
Waterfall provides out of the box replication capabilities for dozens of industrial applications, including process historians, process databases, control system servers, OPC servers, and low-level devices.
Replication solutions are also available for file servers, mail servers, print servers, SIEM servers and other components essential to the integration of modern operations networks with business networks.
The server-replication process is transparent to external users, and has no effect on the original operations servers. External users access and use the replica servers in the same way they accessed and used the original operations servers, without changing working procedures.
