METHOD AND SYSTEM FOR DDOS TRAFFIC DETECTION AND TRAFFIC MITIGATION USING FLOW STATISTICS

摘要

Disclosed are a method and system for distributed denial of service (DDoS) attack detection and traffic mitigation using flow statistics. The method for DDoS attack detection and traffic mitigation using flow statistics includes: collecting first statistics for each flow based on flow information generated by traffic flow of a network connection device; and grouping the first statistics for each flow on a per-flow basis and processing the same into second statistics containing at least one of the number of bytes, the number of packets, and the number of flows per unit time.
