Dan Farmer's Internet Security Survey

Dan Farmer is a leading, although controversial, Internet security expert. Farmer authored the SATAN tool for scanning and exposing network and Internet vulnerabilities. Farmer's "Internet Security Survey" is compiled from an audacious and unsolicited scan of Internet Web sites he conducted in 1996.

According to Farmer, the "red" designation refers to sites that are "wide open to any potential attacker," and the "yellow" designation refers to sites that have "problems that are less serious although still of great concern."
