A Content Delivery Network is a geographically distributed group of servers that caches and delivers web content from locations closest to users. CDNs reduce latency, absorb traffic spikes, and provide DDoS protection by distributing requests across many edge locations worldwide.
CDNs are a frontline DDoS mitigation tool. Security engineers configure CDN WAF rules to block malicious traffic at the edge before it reaches origin servers. Misconfigured CDN caching can accidentally expose sensitive data. Understanding CDN architecture helps security architects design resilient, protected web applications.
