A deep-dive into Cloudflare’s autonomous edge DDoS protection
Mar 18, 2021Omer Yoachimik
Summary
Introduced an autonomous edge DDoS protection system powered by the 'dosd' daemon, deployed across all 200+ data centers. This system detects and mitigates L3-7 DDoS attacks in real-time using eBPF programs in L4Drop and iptables for wire-speed packet dropping. It complements existing core detection mechanisms like Gatebot by enabling faster, more localized attack detection and mitigation.
