What is the difference between volumetric, protocol, and application-layer DDoS attacks?

Volumetric attacks (UDP floods, ICMP floods) overwhelm bandwidth capacity — measured in Gbps/Tbps. Protocol attacks (SYN floods, Ping of Death) exploit protocol weaknesses to exhaust connection tables. Application-layer attacks (HTTP floods, Slowloris) target web server resources with low-volume, legitimate-looking requests. Each requires different mitigation techniques and inspection depths.

How do enterprises implement always-on DDoS protection versus on-demand scrubbing?

Always-on DDoS protection routes traffic through scrubbing centers continuously, providing instant protection but adding latency (10–30ms) and cost. On-demand scrubbing redirects traffic only during attacks via BGP announcement — zero baseline latency but detection-to-mitigation takes minutes. Critical financial, gaming, and government infrastructure typically uses always-on protection.

What DDoS protection features should enterprises look for beyond basic volumetric mitigation?

Advanced DDoS protection features include: L7 protection with WAF integration, bot mitigation for application-layer attacks, anycast BGP for network-layer protection, real-time attack analytics and dashboards, DDoS Response Team (DRT) availability for complex attacks, and DDoS cost protection (AWS Shield Advanced reimburses scaled EC2/CloudFront costs during attacks).
