 ## Validation Failure Action
 
-The `validationFailureAction` attribute controls admission control behaviors for resources that are not compliant with a policy. If the value is set to `Enforce`, resource creation or updates are blocked when the resource does not comply. When the value is set to `Audit`, a policy violation is logged in a `PolicyReport` or `ClusterPolicyReport` but the resource creation or update is allowed. For preexisting resources which violate a newly-created policy set to `Enforce` mode, Kyverno will allow subsequent updates to those resources which continue to violate the policy as a way to ensure no existing resources are impacted. However, should a subsequent update to the violating resource(s) make them compliant, any further updates which would produce a violation are blocked.

This behaviour can be disabled using `validate.allowExistingViolations`, when `validate.allowExistingViolations` is set to `false` in an `Enforce` mode validate rule, updates to preexisting resources which violate that rule will be blocked.
