Talk Title: The Evolution of Internet Threats: A Case for Security

in the Network Cloud

Talk Abstract:
Threats to the availability a

nd security of the Internet have
undergone a rapid and dramatic evoluti

on over the past few
years. Highly visible attacks against Internet use

rs and infra-
structure began only a few short years ago with the emerge

of Internet Denial of Service (DoS) attacks and highly virulent
Internet worms. Today we are in the middle of a fundamental
shift fro

m attacks that primarily target infrastructures to coordi-
nated attacks
launched from a malicious service platform (botnet)
that harvest the r

esources of infected hosts (bots). Spurred by
financial gains attacker

s have become proficient at hiding
themselves using compromised hosts a

s proxies and amplifying
the power of their attacks using distributed s

oftware. The result
is vast numbers of compromised computers or bots
sitting in
homes schools businesses and government networks around

the world enabling a rapid increase in spam phishing and identity
theft. These challenges illustrate how we are at the limits of existing detection and mitigation technologies. In this talk I will introduce a <

br>new security model for networked environments inspired by successful
detection and mitigation solutions in the service provider environment. <

br>The key insight is use of multi-resolution distributed sensors deployed

inside the network and on end hosts that integrate data from different<

br>perspectives to reason about the security of the network as a whole.
To illustrate the utility of this model we will discuss results from two

experimental projects that enable security as a service in the network

cloud: the Dark Oracle and CloudAV.

Speaker Bio:
Farnam Jahan

ian is Professor and Chair of Computer Science and
Engineering at the U

niversity of Michigan and co-founder of Arbor
Networks Inc. Prior to j

oining academia in 1993 he was a Research
Staff Member at the IBM T.J.
Watson Research Center. His research
interests include distributed com

puting network security and network
protocols and architectures. In

the late 90’s Farnam led a research
effort aimed at developing a
flow-based system for detecting back-
tracing and resolving network-wi

de anomalies such as DDoS attacks
and routing exploits. This research p

roject has formed the basis of a
commercial technology that has been wi

dely deployed by more than
300 Internet service providers and mission-c

ritical networks protecting
over 70% of Internet transit traffic today

. Farnam holds a master''s degree
and a Ph.D. in Computer Science from

the University of Texas at Austin.
