Adding cybersecurity to legacy industrial networks

By Nick Flaherty www.flaherty.co.uk

Cynash has launched a cybersecurity system for legacy industrial control networks that rely on serial communications protocols such as RS-485 and RS-232.

SerialTap consists of a patented sensing device that passively intercepts serial communications on legacy industrial control networks. This provides a deeper level of communications transparency and verification to these legacy control systems with analytics software that identifies anomalous network traffic associated with cyberattacks.

“The vast majority of our critical energy, transportation and industrial infrastructure still runs on control networks that rely on serial communications. These networks have absolutely no intrinsic resistance to cyberattacks,” said Richard Robinson, CEO of US-based Cynash. “SerialTap provides a deeper level of communications transparency and process verification to these legacy control systems.”

The technology was developed by the Pacific Northwest National Laboratory, and the sensor is electrically isolated from the control network, preventing any possibility of interference. All intercepted serial data packets are sent to the analytics platform via an out-of-band Ethernet connection.
