Background
A web access control list (web ACL) gives you fine-grained control over the web requests that your Amazon API Gateway API, Amazon CloudFront distribution or Application Load Balancer responds to. Global Web ACLs apply to CloudFront and API Gateway. Regional Web ACLs apply to load balancers.
WAF Regional and Global ACLs are represented in the same fashion, the distinction is made to assist in writing rules for the correct scope.
