Details: This session will focus on mapping the Internet and Intranets
         and how to use this information to protect against intrusion.
         Internet mapping has historically provided a rich source of
         information for research and infrastructure studies, and can
         now be used by organizations to discover the extent of their
         intranets and extranet connections. Attendees will learn how
         mapping and network visualization can be used to explore very
         large networks to analyze perimeters, search for leaks,
         identify threats, and monitor activity.

         Cheswick has worked for nearly 30 years on operating-system
         security. He is the author of one of the most highly regarded
         security books "Firewalls and Internet Security," and is
         currently working on its second edition. Prior to joining
         Lumeta, he was at Lucent/Bell Labs for 13 years and, before
         that, spent nine years with System Computer Technology
         Corporation.
