Software-Defined Networking (SDN) has become an emerging solution to existing virtualized networking problems. Major contributors to the use of SDN is sought through the growing scale of computing power and clustered virtualization solutions. The use of SDN has shown much momentum in newer iterations of hypervisors and provides an area of discussion for vulnerability research. This talk provides a brief introduction to SDN, its components of a switch and a controller, and vectors for fuzzing. To facilitate the focus of SDN in an open source configuration, Floodlight, Open vSwitch (OVS) and the Open Flow protocol will be the prime targets for this talk. Although there are numerous vendor-specific variants, this talk is tailored to individuals who are new to the SDN paradigm, and those who want to learn more about vulnerability research in SDN.
