Abstract
A computer implemented method for providing security on a software defined network (SDN). The method comprises providing a master SDN controller for managing data flow control on the SDN network. Requesting access to a uniform resource locator (URL) from a requesting networked device. Initiating a domain name system (DNS) interaction with the requesting networked device. Relaying by the DNS data associated with the requested URL to a threat management control system (TMCS). Determining by the TMCS if the requested URL has an associated security criteria. Communicating a threat status by the TMCS to the SDN co-controller associated with the requesting networked device.
