Abstract (in Japanese) (See Japanese page) 
(in English) A security threat to IoT system is increasing and attacks to infrastructure can cause serious damage. However, a security measure applied to a personal computer cannot always be applied to a device deployed in a field area. Therefore, we need to operate an IoT system securely without changing devices. We have proposed a network control method of isolating a suspicious device performing abnormal communication in order to operate IoT system securely. However, isolation by network control can make normal devices unable to communicate with others. Moreover, a suspicious device performing wireless communication can connect again by handover after isolation. To solve these problems, we propose a selection algorithm of both network equipment to be controlled and control details appropriate for isolation of a suspicious device. In our method, a gateway, which connects LAN and FAN for managing FAN, manages network topology and suitably controls network equipment so as to minimize negative effect on normal devices such as impossibility of communication, based on the topology. We implemented our method and verified its feasibility by means of actual network equipment.
