Ches has been out and about in the Internet security field since the late 1980s. He is known for his early work in firewalls and proxies, and for the book he has co-authored with Steve Bellovin and now Avi Rubin. In summer 2000 Ches helped spin off the Internet cartography work he did at Bell Labs with Hal Burch into a startup, Lumeta Corporation, which explores the extent and perimeter hosts of corporate and government intranets.
