Okay, this is actually one of the coolest things I've seen in a while. According to the site:
SecurityDocs.com is a directory of information security articles, white papers, and other documents that information security professionals find useful.
I spent a little bit of time earlier browsing the site, and it looks like there's some REALLY good content on here, covering everything ranging from firewall rulesets to OS hardening to security awareness. Very cool.
