Research And Design Of Network And Information Security Audit System

Computer network is gradually changing people's work and life style. As an important characteristic of modern society, information medium has become one of topics of development. However, the environment of computer network is subject to attack. It's unimaginable that what will happen if the network suffers attacks and intrusions. Moreover, the Information Sea from Internet gives people many security problems of information content as well as more convenience.Facing this kind of actuality, many governments and enterprises have to attach importance to the network security. Security auditing is a necessary mechanism in security system. There have been many Network Security Auditing Tools, which mainly consider network intrusion, and their function on information content auditing is limited and not ideal. This thesis researches above two aspects, mix them into one system, and meet the demand of network information security troubles.This thesis compares and chooses the scheme on the basis of analyzing network mechanism, and accomplishes the development and realization of system. Concerning the function, the system emphasizes the audit of network information; On the frame designing, the system adopts the B/S (Browser/ Server) mode, in order to give more flexibility and convenience to system operation and management; About the algorithm designing, the system improves the standard one, and increases the efficiency of program running; In the programming, the system takes advantage of the plug-in mechanism, so as to make the code more cohesive, and let the system easy to be extended and utilized.
