Best paper award at the Symposium on SDN Research

The paper titled "Taking Control of SDN-based Cloud Systems via the Data Plane" by Kashyap Thimmaraju, Bhargava Shastry, Dr.-Ing Tobias Fiebig, Felicitas Hetzelt, Prof. Dr. Jean-Pierre Seifert, Prof. Dr. Anja Feldmann and Prof. Dr. Stefan Schmid received the best paper award at the ACM Symposium on SDN Research (SOSR) 2018, the premier venue for SDN research.

The paper is a result of collaboration between the Security in Telecommunications and Internet Network Architecture Chair at TU Berlin. The paper discusses how an attacker can easily gain privileged and remote access to an entire SDN-based cloud system, thereby compromising the security of the cloud tenants and the cloud provider. The authors cast light on the insecurities of virtual networking that can be leveraged by an attacker in and SDN-based cloud. Virtual networking is a crucial requirement for cloud providers such as Amazon, Google, Microsoft and Detusche Telekom to isolate their tenants from each other. The attack was demonstrated using Open vSwitch and OpenStack, an open-source SDN-based cloud system. A preliminary version of the paper appeared in the ACM Cloud Computing Security Workshop 2017.
