In recent years, countries around the world have placed increasing importance on critical infrastructure, as it not only enhances social welfare and benefits people's interests, but also makes it a target for malicious attackers due to its nature. Therefore, protecting critical infrastructure has become a top priority for many countries. With the emergence of the need for reducing manpower and remote control, balancing critical infrastructure security has become an important issue. This platform is funded by the Future Cybersecurity Deep Cultivation Project of the National Science Council. Recognizing the lack of a comprehensive water infrastructure cybersecurity testing platform in Taiwan, the project team received support from the National Science Council and the Water Resources Agency of the Ministry of Economic Affairs to establish a cybersecurity testing platform for dam gate control systems based on real field equipment. The project uses new generation transmission technologies such as Software Defined Networking (SDN) to enhance security and stability in the transmission stage. In addition, data processing is also critical, and we focus on operational safety by using blockchain technology to secure data. Finally, we conduct various activities such as industrial control system specifications and attack trees during the implementation phase, and have relevant exchanges and competitions. Through multiple synchronizations, the cybersecurity protection environment for key water infrastructure is improved. Ultimately, we hope to gradually expand this project to a more comprehensive water infrastructure cybersecurity testing platform, so that researchers can have a more suitable and complete testing platform for future water-related research.
