Abstract
Recently, cybercrime attacking the national network has increased. National infrastructure such as water purification plants, power plants, and substations are operated by using programmable logic controllers (PLC). PLC controls through the Industrial Control Systems/Supervisory Control And Data Acquisition (ICS/SCADA), which receives operational commands and sends operational states by communication means such as Ethernet and Modbus. However, the environment of ICS/SCADA, called Industrial IoT, is vulnerable to security attacks unlike recently developed technologies such as IoT devices, systems, and networks. Therefore, this study proposes a new security system to strengthen industrial firewalls. We developed an interface, unauthorized access blocking algorithm, and real-time defense system for system access control. The performance of the proposed system was verified by external organizations. Five performance indicators were measured to validate the proposed system. All indexes were achieved to 100%. We hope that this study and results will help block and defend against cyberattacks.
