一种全局的SYN Flood防御方法

he paper presents a brand-new internet defence method for SYN Flood attack, which can detect the attack at the victim’s network and drop attack packets at source networks at the same time. By using anomaly detection method our system can adapt to complicated situations in networks. Besides, we use 6-sigma method to identify the thresholds, which is powerful and successful without beting inordinately cumbersom. Our method can almost detect all the SYN Flood attacks whthin areas it covers.
