OWASP ModSecurity Core Rule Set (CRS)

The OWASP ModSecurity CRS Project's goal is to provide an easily "pluggable" set of generic attack detection rules that provide a base level of protection for any web application.


The OWASP ModSecurity CRS is a set of web application defense rules for the open source, cross-platform ModSecurity Web Application Firewall (WAF).


The OWASP ModSecurity CRS provides protections if the following attack/threat categories:

  • HTTP Protection - detecting violations of the HTTP protocol and a locally defined usage policy.
  • Real-time Blacklist Lookups - utilizes 3rd Party IP Reputation
  • HTTP Denial of Service Protections - defense against HTTP Flooding and Slow HTTP DoS Attacks.
  • Common Web Attacks Protection - detecting common web application security attack.
  • Automation Detection - Detecting bots, crawlers, scanners and other surface malicious activity.
  • Integration with AV Scanning for File Uploads - detects malicious files uploaded through the web application.
  • Tracking Sensitive Data - Tracks Credit Card usage and blocks leakages.
  • Trojan Protection - Detecting access to Trojans horses.
  • Identification of Application Defects - alerts on application misconfigurations.
  • Error Detection and Hiding - Disguising error messages sent by the server.

what is this project?
Name: OWASP ModSecurity Core Rule Set Project (home page)
Purpose: ModSecurity is an Apache web server module that provides a web application firewall engine. The ModSecurity Rules Language engine is extrememly flexible and robust and has been referred to as the "Swiss Army Knife of web application firewalls." While this is certainly true, it doesn't do much implicitly on its own and requires rules to tell it what to do. In order to enable users to take full advantage of ModSecurity out of the box, we have developed the Core Rule Set (CRS) which provides critical protections against attacks across most every web architecture.

Unlike intrusion detection and prevention systems, which rely on signatures specific to known vulnerabilities, the CRS is based on generic rules which focus on attack payload identification in order to provide protection from zero day and unknown vulnerabilities often found in web applications, which are in most cases custom coded.
