Our mission it to conduct critical analyses of the security challenges that are posed by the SDN paradigm and embodied in the current OpenFlow specification.  We are actively working toward solutions to these core challenges, developing reference implementations of OpenFlow security features that can be integrated at all layers of the OpenFlow stack.

We also present reference implementations of advanced network  security defenses that utilize OpenFlow to introduce the next generation of network attack mitigation.  OpenFlow has some truly exciting potential to drive new innovations  in intelligent and dynamic network security defenses for future networks. In fact, long term OpenFlow could prove to be one of the more impactful  technologies to drive a variety of new network defense solutions.
