SerialTap (photo) is a new cybersecurity solution for legacy industrial control networks that rely on serial communication 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 and complementary analytics software that identifies anomalous network traffic associated with cyberattacks. The SerialTap 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. — Cynash Inc., McLean, Va.
