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.
