Due to the spread of Internet of Things (IoT) devices, IoT security management has become important for network administrators. However, security functions are difficult to implement into IoT devices. We thus propose a security system that controls anomaly traffic as a network function. This system is installed in a gateway close to an IoT device. It automatically generates the control rules for each IoT device with user support and improves the accuracy of information sharing between gateways. By distributing the gateway processing, the system prevents processing load and control authority from concentrating at the central server while reducing the cost of using the server. We also present the system's architecture and discuss the evaluation of its performance.
