2021 National Cyber Summit
During these uncertain and unprecedented times, the NCS organization has been faced with a very difficult decision regarding our 2020 Summit. For the safety and well-being of our attendees and exhibitors, as well as preserving the unprecedented networking opportunities NCS provides, we have postponed the 2020 Summit until June 8-10, 2021.

Analyzing the Vulnerabilities Introduced by DDoS Mitigation Techniques for Software-Defined Networks
Wednesday, June 5, 2019 4:35 p.m. - 5:00 p.m.
Software defined networking facilitates better network management by decoupling the data and control planes of legacy routers and switches and is widely adopted in data center and production networks. The decoupling of control and data planes facilitates more optimal network management and deployment of more elaborate security mechanisms, but also introduces new vulnerabilities which could be exploited using distributed denial of service (DDoS) attacks. In this talk, we identify several protocol vulnerabilities and resource limitations that are exploited by DDoS attacks. We analyze the vulnerabilities introduced by several DDoS mitigation techniques, discuss attacks that exploit them, and quantify their impact on the network performance using experiments on a 5-node testbed. We show an approach to mitigate such vulnerabilities while minimizing the introduction of any exploitable vulnerabilities.
