Enterprise DDoS Mitigation: BGP Anycast Routing & Layer 7 Scrubbing
Reviewed by Cloud Infrastructure & Hosting Architecture Editorial Board
Executive Summary
Protecting origin servers: absorbing volumetric SYN floods, UDP amplification, and HTTP flood attacks using distributed edge Anycast scrubbing centers.
Distributed Denial of Service (DDoS) attacks have evolved from simple network-layer floods to sophisticated Layer 7 HTTP request storms designed to exhaust application backend pools.
1. Multi-Layer Mitigation Strategy
| Attack Layer | Common Attack Vectors | Mitigation Architecture |
|---|
| Layer 3 / 4 (Volumetric) | SYN floods, UDP reflection, NTP amplification | BGP Anycast routing, automated Flowspec, edge null-routing |
| Layer 7 (Application) | HTTP GET floods, slowloris, XML-RPC spam | WAF challenge pages, rate limiting, CAPTCHA, edge caching |
| Origin Concealment | Direct IP bypass attacks | GRE tunnels, Cloudflare Magic Transit, private VPC peering |
