Summary
This post introduces Gatebot, an automated mitigation system designed to handle large-scale DDoS attacks. It details the evolution from manual SRE intervention to an automated 'detection/logic/mitigation' pipeline. The post explains various mitigation techniques employed, including scattering, iptables extensions, kernel bypass with floodgate, and HTTP-layer adjustments. It highlights how Gatebot's automation improves response time, precision, and allows for consistent DDoS protection for all users, and notes the reuse of this model in other systems like the Automatic Network System.
