A defense model—ULDM(user loyalty defense model)for the application layer DDoS(App-DDoS)attack was proposed based on the user loyalty.Normal users and attack users were identified based on the degree of loyalty.The user loyalty consisted of the access frequency loyalty and the behavior loyalty.The behavior loyalty included the history behavior loyalty and the current behavior loyalty.The performance of user behavior was evaluated through the request frequency and the ratio of high load request in a long time,and then the user behavior loyalty was obtained.The access frequency loyalty was computed based on the access frequency of each user.Through policy dispatching,the request was scheduled based on the user loyalty.Simulation results show the effectiveness of the defense model.
