Deploy a managed ruleset with ruleset, tag, and rule overrides

Customize the execution of managed rulesets with a combination of ruleset overrides, tag overrides, and rule overrides in your phase entry point ruleset.

  1. Add a rule to a phase entry point ruleset to execute a managed ruleset.
  2. Configure a ruleset override that disables all rules in the managed ruleset.
  3. Configure a tag override that sets an action for rules with a given tag.
  4. Configure a rule override that sets an action for the rules you want to execute.

The request below uses the Update ruleset operation to execute the following in a single PUT request:

  • Add a rule to the http_request_firewall_managed phase entry point ruleset that executes a managed ruleset.
  • Use category overrides to enable rules with wordpress and drupal tags and set their actions to log.
  • Add a rule override that enables a single rule.
Example: Execute a managed ruleset at the zone level with overrides

In this example:

  • "id": "<MANAGED_RULESET_ID>" adds a rule to the http_request_firewall_managed phase entry point ruleset to execute a managed ruleset for requests addressed to a zone ({zone_id}).
  • "enabled": false defines an override at the ruleset level to disable all rules in the managed ruleset.
  • "categories": [{"category": "wordpress", "action": "log", "enabled": true}, {"category": "drupal", "action": "log", "enabled": true}] defines an override at the tag level to enable rules tagged with wordpress or drupal and sets their action to log.
  • "rules": [{"id": "<RULE_ID>", "action": "block", "enabled": true}] defines an override at the rule level that enables one individual rule and sets the action to block.
