Which of the following is the BEST method for mitigating DDoS attacks on a web server?
Virtual Private Network (VPN)
Rate-limiting
Firewall
Content Delivery Network (CDN)
Using a Content Delivery Network (CDN) is effective in mitigating Distributed Denial of Service (DDoS) attacks because it distributes network traffic across multiple servers and locations, helping to absorb and mitigate excessive traffic loads. While rate-limiting can help manage traffic, it may not be sufficient for large-scale DDoS attacks. Firewalls protect against unauthorized access but are not specifically designed to handle the massive traffic flows typical of DDoS attacks. VPNs are used for secure communications and do not mitigate high traffic loads.
