Enterprise network security assessment is a complicated project. This thesis firstly introduced the development of network security assessment and its regular criteria and common schemes. Through deep analysis on the present development of network security and experiments, based on the practical needs, the author gave a further study on each cause affecting network security by comparing different criteria. The basic aim of this thesis was to establish a comprehensive assessment program. The author also pointed out in the thesis the ANN mode based on BP, which had been realized by using VB. It was proved that such kind of assessment mode could give a comprehensive assessment on enterprise network security degrees, and reduce the subjective effects on assessing. It was also helpful for users to find out the weak points of network security, and to adjust security strategies and investment, then promote the security level and make more profits.At last, the author tried to suggest some new thoughts and methods for generally assessing on enterprise network security.
