Cybersecurity for Legacy Industrial Networks

The device intercepts serial communications and uses complementary software to identify network traffic associated with cyberattacks.


Cynash (McLean, VA) offers their SerialTap cybersecurity solution for legacy industrial control networks that rely on serial communications protocols such as RS-485 and RS-232. The patented sensing device passively intercepts serial communications on legacy industrial control networks and complementary analytics software that identifies anomalous network traffic associated with cyberattacks. Based on technology developed by the Pacific Northwest National Laboratory, the SerialTap sensor is electrically isolated from the control network, preventing interference. All intercepted serial data packets are sent to the analytics platform via an out-of-band Ethernet connection.
