The Computer Network System Security Analysis And Assessment

With the development of the Information Tecnology, Computer Networks have been widely used in many fields. But people are anxious for the security of the computer networks more and more. Recent years, more than 60% user networks have been inbreaked. The computer networks have the great risk.The desire of the networks for different type of users is different. The network engineers usually construct a computer network according to their experience and the requests of the user. Qualitative analysis of the security for a network is often used.This paper present to analyze the security of the networks quantitatively using a mathes decision-making method to help people make better decision in building their computer network.There are there parts in this paper. In the first part, this paper gives a introduction to concepts characteristics and the method of the management for the computer network security; The second part introduce the basic methods and principle for the math decision-making method( The Analytic Hierarchy Process-AHP). In the last part, two networks for different users are showed how to process a quantitative analysis for the network security using this AHP method .
