Guidelines on Securing Public Web Servers
I just came across this very comprehensive PDF from NIST (National Institute of Standards and Technology). It’s a 142 page document that covers everything from securing the operating system and the web server to securing web content. This document is part of NIST’s Special Publications (800 Series) – documents of general interest to the computer security community. Highly recommended.
The guidelines are extensive but pretty high level. It mentions robots.txt and ensuring that search engines don’t follow certain links. But it doesn’t specifically address the problems of selling digital products through ClickBank, PayPal and other payment processors. To ensure that your digital products are not indexed by search engines and downloaded for free, I still recommend my Digital Security Report.
