A Method of Detecting Hidden Ports Based on SDN

This paper proposes a method of hidden-ports detection based on SDN, with the characteristics of controlling the whole network, the controller could retrieve all the sessions' information, combined with the customized data received from proxy, the controller could find all the sessions from hidden-ports based on the cross-view of full information and visible information. As the experiment shows, this method could detect all the hidden-ports effectively and compatibly.
