  Hello :) I don't believe the rules provided by OWASP are intended to be copy/pasted into a Mod_Security configuration without first fine tuning them. I will leave this thread open for input from other users who may have implemented the OWASP rules. Thank you.

  Using the OWASP rules is somewhat advanced and you should read the included documentation very carefully. The rules are split into several files. Usually what you do is have a directory for the rules files you want to use. Some rules (protocol anomolies especially) are more prone to false positives than others. Normally if you deploy the entire core rule set you should be prepared to troubleshoot false positives for a while until you get it tuned for your own use. You need a basic modsec2.user.conf to call your own setup config as well as the rules you want to use. My modsec2.user.conf when I used to use the owasp rules looked like this: SecUploadDir /tmp SecTmpDir /tmp SecDataDir /tmp SecRequestBodyAccess On Include "/usr/local/apache/conf/OWASP/10_setup.conf" Include "/usr/local/apache/conf/OWASP/activated_rules/*.conf Include "/usr/local/apache/conf/OWASP/custom.conf" Include "/usr/local/apache/conf/OWASP/exclude.conf"
  Inside the /usr/local/apache/conf/OWASP/activated_rules/ directory were symlinks to the actual OWASP rules files I wanted to use. Custom.conf was for my own rules, and exclude.conf was used for whitelisting problematic rules.

  The atomicorp rules were great for protecting most common CMSes, but the free delayed rules are no longer available. You might consider atomicorp's paid rule set.
