The initiative forecast defense technique of Web application based on HttpModule

The technique of Web application based on the feature code database can only defense the general and known attacks, when the attacks are varietal or not defined by feature, it´s protective effect is poor, and may even lead to the problem of high false positives and false negatives. The proactive defense technique of web application based on HttpModule is put forward in this thesis. It can forecast the attacks in advance and defense without analyzing samples or updating feature code database. The experimental results show that this technique has a good performance of the proactive defensive.
