CDN Security

CDN (Content Delivery Network) security refers to the security capabilities provided by CDN providers, including DDoS mitigation, WAF, bot management, TLS termination, and edge caching. CDNs like Cloudflare, Fastly, and Akamai sit in front of origin servers, absorbing attacks before they reach infrastructure. Proper CDN security configuration includes locking down origin server access to CDN IP ranges only. CDNs also improve security by serving content over HTTPS at the edge even when origin may not support it.
