1. An unauthorized communication coping system that performs unauthorized communication coping which is coping with unauthorized communication detected by an unauthorized communication detection device that performs unauthorized communication determination which is determination of whether or not communication is unauthorized communication based on a packet, the system comprising:
a routing device that performs routing of a packet in conformance with a wireless communication protocol in a wireless communication section which is a communication section that connects a base station and a core network device, the routing device performing network tapping on a packet as a routing target and transmitting the network-tapped packet to the unauthorized communication detection device; and
an unauthorized communication coping device that performs, for unauthorized communication which is communication for which a result of the unauthorized communication determination based on the network-tapped packet is true, unauthorized communication coping including configuring communication control information which is information for controlling the unauthorized communication for at least one of the routing device and the core network device; wherein
the core network device is connected to the wireless communication section and an IP communication section,
the IP communication section is a communication section in which communication according to an IP is performed,
the unauthorized communication detection device is a device that specifies an IP address of each of a transmission source and a destination based on the network-tapped packet,
the unauthorized communication coping device specifies a device ID corresponding to an IP address for at least one of a transmission source and a destination of the detected unauthorized communication based on IP-SIM information which is information indicating a correspondence relationship between the IP address and the device ID, and
the unauthorized communication coping includes configuring communication control information which is information for controlling communication of a device identified from the specified device ID for at least one of the routing device and the core network device.
