AWS WAF
AWS WAF is a web application firewall that lets you monitor the HTTP(S) requests that are forwarded to your protected web application resources. You can protect the following resource types:
Amazon CloudFront distribution
Amazon API Gateway REST API
Application Load Balancer
AWS AppSync GraphQL API
Amazon Cognito user pool
AWS App Runner service
AWS Verified Access instance
AWS WAF lets you control access to your content. Based on criteria that you specify, such as the IP addresses that requests originate from or the values of query strings, the service associated with your protected resource responds to requests either with the requested content, with an HTTP 403 status code (Forbidden), or with a custom response.
Note
You can also use AWS WAF to protect your applications that are hosted in Amazon Elastic Container Service (Amazon ECS) containers. Amazon ECS is a highly scalable, fast container management service that makes it easy to run, stop, and manage Docker containers on a cluster. To use this option, you configure Amazon ECS to use an Application Load Balancer that is enabled for AWS WAF to route and protect HTTP(S) layer 7 traffic across the tasks in your service. For more information, see Service Load Balancing in the Amazon Elastic Container Service Developer Guide.
