Jing Wu · Communications technology · 2012
With the increasing complexity,transparency and code of Ajax technology,the attack surface and possibility of information leakage for Ajax application system is greatly enhanced.Aiming at the loophole characteristics of and aggressive behavior against Ajax structure,this paper,from the content of data packets payload,analyzes and studies the anomalous request packet by Ajax,summarizes the characteristics of anomalous data packets of Ajax,and the feature extraction is implemented with the improved BM algorithm.Finally an anomaly judgment on these extracted characteristics is done through the evaluation algorithm.The experimental results show that,compared with the traditional intrusion detection methods,the Ajax anomaly detecting technology proposed in this paper could accurately and efficiently complete the detection of Ajax anomalous request.
