Adobe published the work of Pete Freitag today - a 35 page guide to secure installation and configuration of ColdFusion. Even if you feel like your ColdFusion server(s) are tightened up, it's always a good idea to take a moment to do a review.

While the guide does not go into detail on building secure applications, Pete's PDF is a step-by-step tutorial that even someone not familiar with ColdFusion administration could follow. Grab the PDF and spend the 15 minutes to check up on all of your servers (including your local development environment) - it's well worth it.

When you're done with that, check out the Security section of the ColdFusion Developer Center on the Adobe Developer Connection for lots of articles on how to write safe and solid code too!
