OWASP stands for Open Web Application Security Project. OWASP ModSecurity CRS (Core Rule Set) is a set of web application rules used to protect the server. It uses configuration file to set these rules. OWASP ModSecurity CRS increases the amount of protection for web applications. It acts as a baseline protection for common web application attacks. These rules are easily pluggable.

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