Use rulesets and rule overrides to only enable selected rules
Use a ruleset override and a rule override in a phase entry point ruleset to execute only selected rules in a managed ruleset.
- Add a rule to a phase entry point ruleset that executes a managed ruleset.
- Configure a ruleset override that disables all rules in the managed ruleset.
- Configure a rule override to set an action for the rules you want to execute.
Example: Configure ruleset and rule overrides at the zone level
The following PUT
request uses the Update ruleset operation at the zone level to execute only two rules from a managed ruleset in the http_request_firewall_managed
phase.
In this example:
"id": "<MANAGED_RULESET_ID>"
adds a rule to the phase entry point ruleset to execute a managed ruleset for requests in the specified zone ({zone_id}
)."enabled": false
defines an override at the ruleset level to disable all rules in the managed ruleset."rules": [{"id": "<RULE_ID_1>", "action": "block", "enabled": true}, {"id": "<RULE_ID_2>", "action": "log", "enabled": true}]
defines a list of overrides at the rule level to enable two individual rules.

Example: Configure ruleset and rule overrides at the account level
The following PUT
request uses the Update ruleset operation at the account level to execute only two rules from a managed ruleset in the http_request_firewall_managed
phase.
In this example:
"id": "<MANAGED_RULESET_ID>"
adds a rule to the phase entry point ruleset to execute a managed ruleset for requests addressed toexample.com
."enabled": false
defines an override at the ruleset level to disable all rules in the managed ruleset."rules": [{"id": "<RULE_ID_1>", "action": "block", "enabled": true}, {"id": "<RULE_ID_2>", "action": "log", "enabled": true}]
defines a list of overrides at the rule level to enable two individual rules.
