Securing Orbital Media's internet edge across a multi-CDN setup on the edge security board: eight tiles — DNS and anycast, TLS and certificates, WAF and rules, DDoS protection, bot management, the API gateway at the edge, origin shielding, and edge logic and observability — each moved from its exposure, such as a single unsigned DNS provider, an expired certificate or a WAF in log-only mode, to its sound design; and the request path from a global audience through both CDNs and the edge gateway to an origin that only the edge can reach, with HSTS confirmed by a header check.

Edge & CDN Security Architecture — The Edge Security Board

A senior-level architecture course that builds the end-to-end security of the internet edge across one or more CDNs. Work the edge security board - eight tiles: DNS & Anycast, TLS & Certificates, WAF & Rules, DDoS Protection, Bot Management, API Gateway at Edge, Origin Shielding, and Edge Logic & Observability - pairing sound design against the exposure it closes, with real DNS/dig, openssl, WAF-and-DDoS-as-code, curl header, and API-gateway drills throughout. Four hands-on activities in every lesson.

What you'll learn

Make DNS resilient, authenticated, and free of dangling records that can be hijacked.
Terminate TLS under a strict policy, force HTTPS, and automate certificates end to end.
Layer managed and custom WAF rules, tune false positives, and virtual-patch fast, as code.
Shield the origin completely and secure edge compute, headers, and telemetry across every CDN.
