What is Content Distribution Network CDN?

Understanding Content Distribution Network CDN

Is a large distributed system of servers deployed in multiple data centers across the internet. A CDN improves website performance by delivering content from servers located closer to users, reducing latency and bandwidth usage. CDNs also provide security benefits through distributed architecture, DDoS protection, and SSL TLS termination. CDN security is addressed in standards like PCI DSS for organizations that process payments. Organizations implement CDN security through access controls, encryption, token authentication, and Web Application Firewall WAF capabilities. For example, an e-commerce company might use a CDN with integrated DDoS protection and a WAF to deliver website content securely while defending against common web attacks.
