Network Firewall and API Gateway : how to ?

Question

Is it useful to use a **Network Firewall** in an **API Gateway** based solution, a **VPC Link** to a private subnet containing a **private ALB** with **ECS services** ?

If yes, how to configure the solution to inspect the flows through the firewall?

Answer

You should definitely use AWS WAF with API Gateway to protect you against well known vulnerabilities such as OWASP - https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-control-access-aws-waf.html

As regards using a Network Firewall for IDS/IPS capabilities, some patterns are discussed here - https://docs.aws.amazon.com/whitepapers/latest/building-scalable-secure-multi-vpc-network-infrastructure/centralized-inbound-inspection.html

You should be able to adapt the API Gateway architecture to fit into these patterns.
