Protecting the Internet Infrastructure

Dr. John "JI" Ioannidis (Columbia University, USA)


ABSTRACT

Most users think of the Internet as the collection of services that are available; mostly the Web, email, and data sharing. All Internet services, however, depend on routers to forward traffic, and links between routers over which this traffic flows. These, the Internet Infrastructure, are increasingly the target of attacks, and protecting them is a much harder problem that protecting end-services. This talk gives an overview the Internet infrastructure, presents the current Distributed Denial-of-Service attacks and Routing attacks that are plaguing it, and discusses current and future research in this area.

BIOGRAPHY

John Ioannidis ("JI") is a Senior Research Scientist at Columbia University. The underlying theme of his research has been protecting large-scale infrastructures. In recent years, he was worked on ways of improving the state of interdomain routing with emphasis on scalable and incrementally-deployable protocols. He has also worked on methods to defend against distributed denial of service attacks, in particular the Pushback mechanism, a self-regulating network-based approach to alleviating congestion caused by DDoS attacks. He has also done extensive work on Trust Management and its applications. Older work includes the original Mobile-IP work, swIPe (the precursor to IPsec), and the original implementations of IPsec for BSD and FreeS/WAN.
