We provide a brief overview of the vulnerabilities present in the OpenFlow protocol as it is currently deployed by hardware and software vendors. We identify a widespread failure to adopt TLS for the OpenFlow control channel by both controller and switch vendors, leaving OpenFlow vulnerable to man-in-the-middle attacks. We also highlight the classes of vulnerabilities that emerge from the separation and centralization of the control plane in OpenFlow network designs. Finally, we offer suggestions for future work to address these vulnerabilities in a systematic fashion.
Benton et al. also present a brief overview of the vulnerabilities in OpenFlow protocol REF .
