Abstract
A controller for software defined networking includes a processor. The processor is configured to receive a first request including a first packet from a first communication partner. The processor is configured to generate an inspection message on basis of the first packet. The processor is configured to send the inspection message to the first communication partner. The processor is configured to monitor whether a first phenomenon occurs with respect to the first communication partner after the inspection message is sent. The first phenomenon is expected to occur when an authorized switch performs a process on basis of the inspection message. The processor is configured to determine, when the first phenomenon does not occur, that the first communication partner is not the authorized switch but an attacker.
