 IMHO, a firewall is necessary as long as you are not running a
 standalone web server with sole access to the Internet. O'Reiley's
 WebSite is an application program running over a largely insecure
 OS platform that will still allow the purposeful prankster to ruin
 your show for a laugh.
 
 The word 'secure', as I looked at it, is history. Anything considered
 secured now is relative to the lack or gain of technology and
 information. And then there is the bugs......
 
 Firewall may not be some screening that you will like, especially
 when the industry is oddly shifting to the WindowsNT platform. But
 it will still reduce the odds that a would-be hacker making
 curtain calls to your website/LAN and provides a misinformed peace
 of mind to your company's MIS. But if you don't like firewalls, try
 reducing the number of active ports to the minimal necessity, and
 delete a whole lot of interesting executables.
 
 Security in a networking environment, afterall, means inconveniences.
