What you should know about firewalls

Scott Rolf knows trouble when he sees it. An IT director for a law firm near Cleveland, Ohio, Rolf was asked by a friend to check out the new Web site the friend had put up on a DSL-connected Web server. Rolf did more than just visit his friend's site; he quickly found that the server lacked any sort of firewall protection. It took less than five minutes for Rolf to exploit a well-known Windows NT vulnerability and e-mail to his friend a complete listing of files and directories from the server's hard disk.

"He called me a few minutes later and said 'Holy cow, what do I do?' He was at work and couldn't turn the server off," Rolf laughs. "I think he went out and bought a Linksys firewall box."
