摘要

PROBLEM TO BE SOLVED: To provide a network for disconnecting illegal communication in physical hierarchy concerning both wired connection and wireless connection.

SOLUTION: The network 1 is the network where a wired switch 800 to which a computer device 700 is connected by wired connection, a wireless controller 500 to which the computer device is connected by wireless connection, a security monitor device 300 for recording the IP address of the computer device in a communication log when the computer device performs the illegal communication, and a communication management device 100 for specifying the computer device performing the illegal communication. The communication management device includes a device retrieval means 130 for specifying the MAC address of the computer device which corresponds to the IP address extracted from the communication log. The wired switch and the wireless controller respectively reject connection from an apparatus having the predetermined MAC address.
