Dear Colleagues,

The expressions "system security" and "denial of service" have never meant so much.

With the media swimming with reports on Web page vandalism, system break-ins, and presidential commissions, recognition of security issues and the creation of protective infrastructures have sent companies scrambling for the latest information, training, and technology. Security professionals know the USENIX Security Symposium has a long track record of presenting leading research results and practical material.

Want to know how to firewall Win2K? What intrusion detection can do for you? How to engineer an appropriate security system? How to buy only as much security as you really need? Attend the in-depth tutorials at the 9th USENIX Security Symposium, given by top-notch instructors such as Dan Geer, Phil Cox, Marcus Ranum, and Avi Rubin.

Keynote Speaker Dr. Blaine Burnham, Director of the Georgia Tech Information Security Center and former NSA program manager, will share his insights into "The Journey Ahead."

This year's technical program welcomes some of the industry's leading experts, including Ian Goldberg, Suelette Dreyfus, Mudge, and Mark Chen. The Work-in-Progress session brings you the latest in research work.

In addition to formal presentations, you'll have plenty of opportunities to meet with peers with similar interests, at Birds-of-a-Feather sessions and several receptions.

Visit the Vendor Exhibition for previews of the latest in security products, services, and solutions.

Whether you are a computer security researcher, an applications developer, or the system administrator everyone counts on to maintain a bulletproof site, this is the one conference you need to attend.

We've assembled what's arguably the strongest program in the history of the USENIX Security Symposium. But don't take our word for it. Join us August 14—17, 2000, in Denver, Colorado.
