DESCRIPTION:Nicolas Christin\, Carnegie Mellon University\nIC faculty cand
 idate\nAbstract\nWith the rise of financially-motivated computer abuse\, u
 nderstanding economic incentives of both attackers and targets has become 
 critical to strengthening online security. In this talk\, I will advocate 
 the need for a broad research agenda\, ranging from network measurements a
 nd analysis to game-theoretic modeling.\nI will first show how empirical n
 etwork measurements help better design intervention mechanisms against att
 ackers. Using the online sale of unlicensed pharmaceutical drugs as a case
  study\, I will describe how longitudinal\, large-scale measurements and a
 nalysis reveal important structural properties of a priori complex crimina
 l ecosystems. I will in particular demonstrate the existence of "choke poi
 nts" both in traffic brokering and product supply\, which should be prime 
 targets for intervention.\nIn addition to disrupting attackers' operations
 \, improving overall network security also requires users strengthen their
  defenses -- but which incentives do they have to do so? I will introduce 
 a game-theoretic model that we developed to describe how rational users re
 spond to security threats in large-scale networks. I will use this model t
 o show how network effects\, specifically negative network externalities\,
  strongly influence security decision making. I will conclude by outlining
  a roadmap for future security research combining measurements\, mathemati
 cal modeling and behavioral aspects.Biography\nNicolas Christin is the Ass
 ociate Director of the Information Networking Institute at Carnegie Mellon
  University\, and a Senior Systems Scientist in CyLab\, Electrical and Com
 puter Engineering\, and Engineering and Public Policy. He holds a Diplôme
  d'Ingénieur from École Centrale de Lille\, and M.S. and Ph.D. degrees i
 n Computer Science from the University of Virginia. After a postdoc in the
  School of Information at the University of California\, Berkeley\, he joi
 ned Carnegie Mellon in 2005. He served for three years as resident faculty
  at CMU CyLab Japan\, before returning to Carnegie Mellon's main campus in
  2008. His research is in computer security and networking\, and spans a b
 road range of interests\, from systems to policy research. He has most rec
 ently focused on online crime\, security economics\, and behavioral aspect
 s of computer security. He equally enjoys field measurements and mathemati
 cal modeling.
