Principle and Defending of DDoS Attack

Distributed Denial of Service Attack(DDoS)is currently used by hackers as a commonly used tool to attack,and such attack on the network caused the increasing dangers.In order to better understand the characteristics of such attack as well as to avoid greater losses,the study of DoS and DDoS attacks′principle is proposed,and some common type of DDoS attack such as Smurf attack,Trinoo attack,makes two innovative DDoS attack detection methods that is feature-based and anomaly-based attack detection.These two detection technology knowledge have their own advantages,in the actual use is often the combination of common DDoS to improve the accuracy of detection.
