Abstract
An unauthorized connection detection system is provided for detecting and addressing unauthorized connection to the network of an improper terminal device without having connection authority by such as spoofing by rewriting an IP address or a MAC address. The terminal device having the connection authority to the network has a dedicated monitoring program product stored therein, to transmit a notification when the connection to the network is started or scheduled correspondence while connected to the network. When a connection startup notification or the scheduled correspondence is not received from the monitoring program product while the connection to the network is permitted by verification of such as the IP address, due to the terminal device connected in an unauthorized manner by spoofing not being provided with the monitoring program product, processing for interrupting communication of the terminal device is performed.
