DDoS Attack Mitigation: SYN Flood, Slowloris & Anycast Absorption.

In Simple Words:

  • SYN Flood (Layer 4): Floods TCP SYN packets without sending final ACK to exhaust connection memory table. Fix: SYN Cookies.

  • Anycast Absorption: Distributes massive attack volume across hundreds of edge locations worldwide.
