flowtrackd: DDoS Protection with Unidirectional TCP Flow Tracking
Jul 14, 2020Omer Yoachimik

Summary
Introduced flowtrackd, a new software-defined DDoS protection system for Magic Transit that implements unidirectional TCP flow tracking. This system uses a state machine to analyze ingress traffic and determine whether to forward or drop TCP packets based on connection state, enabling mitigation of complex TCP-based DDoS attacks that were previously challenging due to the lack of bidirectional visibility. This complements existing stateless and bidirectional stateful mitigation methods.
