This document provides further details about the OWASP Core Rule Set (CRS) rules in the LoadMaster including a list of rule sets and associated ID numbers. All rule sets are enabled by default. Rule groups or individual rules within each ruleset can be enabled/disabled as required. To enable a rule or group of rules, select the relevant check box. If you have previously enabled/disabled rules in a ruleset within a Virtual Service – the rules retain their previous settings.
