In this talk I will describe practical threats and solutions related to malicious (hardware and software) switches in cloud networks. In particular, I will focus on cloud networks that i) consolidate control over the (hardware and software) switches to a logically centralized controller and ii) use virtualization techniques for multi-tenancy. I will present some of my most compelling research from the past 4.5 years which involves work on covert channels in the control plane, and isolation in the data plane. I will talk about the attacks and defenses from a conceptual perspective and then support that using real-world software and/or hardware. If there is time I can also share some demos.

Bio Kashyap Thimmaraju is a PhD student at the Security in Telecommunications chair at the Technische Universität Berlin (TUB) in Germany and is going to start as a Postdoctoral Researcher at the chair of Internet and Measurement and Analysis also in TUB . His paper titled “Compromising the Cloud via the Data Plane” published in ACM Symposium on SDN Research 2018 was awarded the best paper. Before his PhD he was at UC Davis for his Masters and prior to that he worked at Juniper Networks as a test engineer for their router and firewall OS (JUNOS). His research interests lie at the various intersections of networking, systems, security and performance.
