Development of a Testbed for Process Control System Cybersecurity Research

Abstract

Testbed plays an important role in the cybersecurity research of process control system. It helps us design and test solutions to various attacks against control system. A hybrid structure process control testbed, combining programmable logic controllers and other real process control systems with simulated Tennessee-Eastman process, was proposed in this paper. Principles and details of the testbed are described in the paper. Cybersecurity scenario on the testbed through Modbus worm attack was implemented to show the adverse impact on process control system and the industrial process being controlled.
