Data Network Security Monitoring System

As the computer network becomes the important information carrier and translation channel not only for the enterprise but also for the government and all kinds of organizations, people's work efficiency was greatly improved. However, if an effective monitor and manage system is absent, then it is difficult to supply satisfied service for the enterprise user, especially for the enterprise manager. So to monitor and to manage network properly play more and more significant role in the internal network running.To solve the network security and management problem, different organizations and institutions proposed different methods and solutions. But the present network security system mostly puts the research stress on the network border safe technique, which shows insufficiency in dealing with the illegal operation of intramural personnel. Therefore it is needed to supervise the diversiform action and information, in order that the network can be protected safely and orderly.Based on the situation described above, this article focuses on the network security management technology and brings forward the concept of NSMS (Network Safe Monitor and Manage System) which analyses the network safe model hiberarchy and designs the system from the module of two aspects: topological monitor and host computer supervise. At present, the test work of the system has already been carried out in intramural network center and reached expected effect. It is also hoped that the system would be successfully applied to the freeway in the near future.
