Dear Colleague,

Computer security today advances at an exceptional rate, as both its operational relevance and the tension between attackers and defenders continue to grow. New services, new systems, and new networking architectures continually add new dimensions to the field and subvert previously held assumptions. This symposium offers cutting-edge research on topics that range from securing real systems through diagnosing the Net.

The Security training program can help you learn the latest on topics such as:

• Understanding and Addressing the Threat of Internet Worms
• TCP/IP Weapons School
• RFID Security & Privacy

Experts such as Richard Bejtlich, Dan Geer, Vern Paxson, Stefan Savage, Geoff Voelker, Nicholas Weaver and Abe Singer will give you the information, techniques, tools, and strategies you need to practice effective security today—and tomorrow.

Don't miss the keynote address by former senior White House Advisor Richard A. Clarke, Chairman, Good Harbor Consulting LLC.

The Invited Talks cover a number of highly relevant topics, including:

• "Signaling Vulnerabilities in Law Enforcement Wiretapping Systems," by Matt Blaze, University of Pennsylvania
• "Turing Around the Security Problem," by Crispin Cowan, Director of Software Engineering, Novell
• "DRM Wars: The Next Generation," by Ed Felten, Princeton University
• "Surviving Moore's Law: Security, AI, and Last Mover Advantage," by Paul Kocher, Cryptography Research
• And more...

The 22 refereed papers present the best new research in a variety of subject areas, including intrusion detection, system assurance, static analysis for security, and authentication.
