DDoS attacks remain one of the most significant threats to online businesses. This article provides a comprehensive overview of modern DDoS defense strategies.
Attack Types
- Volumetric: UDP floods, DNS amplification, NTP reflection (up to 3+ Tbps)
- Protocol: SYN floods, fragmented packet attacks, Smurf attacks
- Application Layer: HTTP floods, slowloris, DNS query floods
Defense Layers
Effective DDoS protection requires multiple defense layers:
- Network edge: BGP-based null routing and upstream scrubbing
- Scrubbing centers: Dedicated hardware (Arbor Peakflow, Corero) that filters malicious traffic
- Server level: Rate limiting, connection limits, SYN cookies
- Application level: WAF rules, CAPTCHA challenges, behavioral analysis
