A cyber security intrusion detection system for industrial control systems

SwRI designed an industrial network to detect cyberattacks from a malicious computer. The network utilized the Modbus/TCP protocol to transfer data packets between input/output (I/O) devices and programmable logic controllers (PLCs) connected via an Ethernet switch.

Southwest Research Institute has developed technology to help government and industry detect cyber threats to industrial networks used in critical infrastructure and manufacturing systems. SwRI funded the research to address emerging cyber threats in the rapidly evolving ecosystem for industrial automation.

The team used algorithms to scan for cyber threats across network protocols that transmit industrial control …
