OWASP ModSecurity Core Rule Set Version 3.0 Released (modsecurity.org)

Need a new set of generic attack detection rules for your web application firewall? Try the new OWASP ModSecurity Core Rule Set version 3.0.0! Long-time Slashdot reader dune73 writes: The OWASP CRS is a widely-used Open Source set of generic rules designed to protect users against threats like the OWASP Top 10. The rule set is most often deployed in conjunction with an existing Web Application Firewall like ModSecurity. Four years in the making, this release comes with dozens of new features including reduced false positives (by over 90% in the default setup), improved detection of SQLi, XSS, RCE and PHP injections, the introduction of a Paranoia Mode which allows assigning a certain security level to a site, and better documentation that takes the pain out of ModSecurity.
There's rumors this new rule set is even being made into a movie

False Positives mostly gone in CRS3

The ModSec Core Rule Set 3.0 (CRS3) comes with a reduction of at least 90% of false positives (more like 99% on my servers). The base setups of Wordpress and Drupal can be run without any FPs.

If you see FPs with a default install of the Core Rules, please report. The idea is to have next to no FPs in the standard deployment mode.

There is a series of tutorials, which explains the installation of ModSec, the inclusion of the Core Rule Set and the handling of False Positives (still important at higher Paranoia Levels).
