Based On J2ee Vulnerability Scanning System Design

In this thesis, a Vulnerability scanner platform based on distributed system is planned and carried out with J2EE technology.With the development of Internet technology and wildly application of Intranet, the networking security has being highly focused on, and become a important problem of network-application. When people enjoy openness, internationalism and freedom of Internet, they bring forward more security of it.This article firstly systematically discusses the fundamental principle, measure of network security protection and present state of network security, secondly, analysis the vulnerability scanning technology used in detail. The system is constructed taking the scanner server as the core and suitable for trans-platform motion. According to standards of J2EE, the structure of the whole system is based on design pattern of MVC(view, control and data division).On the basis of overall design, the article emphasizes two important technology, and supply the resolution and realization: one is the design of middle-software, it can serve for foreground and connect background scanning server and the data-base. We can achieve the separation of service logic module and specific protocol with a protocol adaptor; the other is combining the expert system's ideas based on rules to accomplish the innovative design about scanning engine in the scanning server, and studying the approach of constructing driving rule-base.At last, the article emphasizes the study for the realizing technique of scanning-server, and expounds the part realization of system. The aim of system is to make the system running efficiency, stability and scanning veracity better.
