Amazon Web Services SCS-C03 Question Answer
A company is running a containerized application on an Amazon Elastic Container Service (Amazon ECS) cluster that uses AWS Fargate. The application runs as several ECS services.
The ECS services are in individual target groups for an internet-facing Application Load Balancer (ALB). The ALB is the origin for an Amazon CloudFront distribution. An AWS WAF web ACL is associated with the CloudFront distribution.
Web clients access the ECS services through the CloudFront distribution. The company learns that the web clients can bypass the web ACL and can access the ALB directly.
Which solution will prevent the web clients from directly accessing the ALB?
