A public API needs a first line of protection against unwanted traffic.

When this becomes useful

A public or shared service needs a defense that matches the actual threat. The example is one layer of that defense; access checks and operational response remain product work.

What the template offers

HTTP API with CloudFront and WAF is a Terraform pattern from AWS Serverless Patterns. It offers a concrete implementation to inspect and adapt. A useful perimeter example. It does not replace authentication, authorization or abuse controls inside the application.

Technical shape

Inspect the CloudFront, WAF and API Gateway connection. Check what traffic reaches the API directly and which rules are enabled.

Questions worth answering

• What threat does this example address?
• Which controls must still live in the application?
• How will rules be observed and updated?
