DoS mitigation and enhanced security

To implement Denial of Service (DoS) mitigation and enhance the security of our application, we can filter traffic with customized security rules, since API Gateway can be integrated with the AWS Web Application Firewall (WAF). The WAF allows us to specify network-based rules and HTTP string-based filters so that we can remove any requests that would otherwise hit API Gateway at the WAF entry point. When the API Gateway endpoint is deployed in an edge-optimized manner, the service will be operating at the CloudFront layer and secure all our traffic at the entry point to our environment. With the WAF, we are able to control the intricate details of each API request, which allows us to protect our backends against malicious scripts, XSS, SQL injection attempts, and malformed queries with a length of query, type of query and any regex pattern...
