Protect Your Web Site with AWS WAF and CloudFront

Protect Your On-Premises Website with AWS WAF and Amazon CloudFront Protecting web applications—regardless of where they run—with a scalable, highly available, and cost-effective edge layer is a cornerstone of modern architecture. This article walks through a hands-on proof of concept (PoC) that leverages AWS WAF for security, CloudFront for global caching and performance, and a serverless pipeline for on-the-fly HTTP context modification. You’ll learn how to: Enhance availability and reduce origin load by caching static and dynamic content at the edge. Secure traffic with AWS WAF rules before it ever reaches CloudFront. Offload requests from the origin to minimize connectivity and costs. Modify any part of the HTTP request or response—including headers, query strings, and body—using a Lambda-powered proxy.
