USC CS Colloquium Series
Thu, Nov 09, 2006 @ 03:30 PM - 05:00 PM
Thomas Lord Department of Computer Science
Student Activity
Dr. Brad KarpUniversity College LondonTitle: Evolution in Action: Worms and Worm DefensesAbstract:Secure systems are interesting to design and build because they face an adaptive, adversarially constructed workload. In this talk, I will trace three years of experience building systems to defend Internet-connected hosts from Internet worms, and the evolutionary pressure exerted on worm designers by defenses.I will first describe Autograph, a system that generates signatures for never-before-seen worms quickly and automatically. A distributed deployment of Autograph would have generated a signature for Code-Red-Iv2 before 2% of vulnerable Internet hosts had become infected (despite the exponential spread of worms, which can scan the entire Internet address space in minutes).The natural response of worm authors to signature-based worm quarantine is to render worms *polymorphic*, so that they change their payloads on every infection attempt, and thus match no single contiguous signature. Motivated by this threat model, I will describe Polygraph, a suite of signature generation algorithms that can be used to automatically generate signatures, even for polymorphic worms.I will finally describe Paragraph, a suite of attacks on signature generation algorithms based on conventional machine learning (sadly, including Polygraph). The attacks in Paragraph are particularly devastating because they are practical attacks on learning *itself*. As conventional learning approaches assume that training examples are random in content, or even designed by a *helpful* teacher, they perform unacceptably when a malicious adversary controls training examples.I will close with a few final musings on how to design signature generation systems immune to Paragraph-style attacks.[This talk will describe joint work with Andrea Bittau, Mark Handley, Hyang-Ah Kim, Jinyang Li, Jim Newsome, and Dawn Song.] Biography: "Brad Karp is an Associate Professor (or "Senior Lecturer," in UK academic parlance) at the Department of Computer Science at University College London. He previously was a Staff Scientist at ICIR (originally ACIRI) at ICSI in Berkeley, a Senior Staff Researcher at Intel Research Pittsburgh, and Adjunct Assistant Professor at Carnegie Mellon University's Computer Science Department. His research marries the design of algorithms and the building of real systems, in the areas of wireless and sensor networks (e.g., GPSR and CLDP for geographic routing), Internet worm quarantine (e.g., Autograph and Polygraph for worm signature generation), and Internet-scale distributed systems (e.g., Open DHT, a public DHT service, and Re:, a system to eliminate false positives caused by spam filtering). Brad holds a Royal Society-Wolfson Reseach Merit Award, given to recruit leading scientists to UK universities."Hosted by: Prof. Ramesh Govindan

New HHMI Graduate Programs - Information Session
Thu, Nov 09, 2006 @ 04:00 PM - 05:30 PM
Thomas Lord Department of Computer Science
Workshops & Infosessions
The Howard Hughes Medical Institute (HHMI) is now launching two Ph.D. programs based at our new Janelia Farm Research Campus, in partnership with the Universities of Cambridge and Chicago. These accelerated programs are designed for a small number of well prepared, highly committed, and gifted students.We are focused on two main goals:· The identification of general principles that govern how information is processed by neuronal circuits· The development of imaging technologies and computational methods for image analysisJanelia Farm opened for operations in August 2006 and we have now recruited nineteen lab heads, with twenty more to be recruited. Their interests include functional neurobiology in worms, flies and rodents, the development of new microscope technologies, protein engineering and computational analysis. Janelia is fully internally funded by the HHMI and labs can have no more than six people for each lab head. Thus the scientific activity is designed to be intense and collaborative.Most students spend one year at their chosen partner institution followed by three years of research work at Janelia Farm. Students will have two mentors: one at Janelia Farm and one at the partner university. They will fulfill the academic requirements of the partner university and their Ph.D. theses will be examined there.Are you ready for this challenge?
To bring your talents and skills to join our intense, collaborative and interdisciplinary team that is working to understand the mechanism of the mind.Learn more about us at: http://www.hhmi.org/janelia/Application deadline: December 15, 2006
