OPC UA TSN Industrial Control System Cybersecurity Testbed

Due to the advent of Industrial 4.0, the Industrial Internet emphasizes the combination and application of IT technology and OT technology, and one of the features of Time sensitive networking is the feature of separating transmission time. This feature will be able to combine IT technology and OT technology in Industrial control systems. But as a result, the issue of information security in the industry is on the rise. In order to research security issue and protection in Time sensitive networking, we have built a test platform support TSN for industrial control networks for related research. Through the experiments in the research, we can know that TSN has a good effect on the separation of general traffic and TSN traffic. TSN won’t be affected by general traffic but is very vulnerable to priority traffic attacks.
