From eWeek: Don't Expect Privacy On The Web
This is an interesting (and scary) article on how lax controls over content on your web server can expose critical information to the world via Google. By using some of the Google search syntax, it's extremely easy to search for credit card numbers within a given range, and pick up files that are truly keys to the kingdom.
Definitely worth a read to make sure you aren't putting yourself at risk.
