This intermediate module explores the critical security controls required to protect Content Delivery Networks (CDNs) and edge computing environments. You will learn how to secure origin servers from direct IP access, prevent cache poisoning and cache deception attacks, configure robust TLS/SSL termination, and harden edge functions (like AWS Lambda@Edge or Cloudflare Workers). By mastering CDN and edge security, you will ensure that your global application delivery remains fast, resilient, and protected against sophisticated distributed and application-layer attacks.
