Description-en: OWASP ModSecurity Core Rule Set
modsecurity provides critical protections against attacks across most every
web architecture. 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.
.
Core Rules use the following techniques: HTTP request validation, HTTP
protocol anomalies, Global constraints, HTTP Usage policy, Malicious client
software detection, Generic Attack Detection (SQL injection, Cross Site
Scripting, OS Command Injection, ColdFusion, PHP and ASP injection, etc.),
Trojans & Backdoors Detection, Error Detection, XML Protection, Search Engine
Monitoring.
