Abstract:

Networks and information systems are now playing more and more important roles in modern society. The network security problem about the system is the chief question which puzzles network managers all the while. The IT industry has brought out the related resolution schemes for this question. The network admission control system developed by several manufacturers can improve network security and reduce network managers’ stress to a certain extent. But in some aspects, the systems look not so funtional and effective, which needs to be enhanced. This article first analyzes the two representative network admission systems, and then gives the optimization project for their flaws. In the optimization project, the resources management system and process procedures will be analyzed, and the function design of the behavior audit and process will be described.
