The paper presents the design and implementation of a large-scale automatic network information machine, the architecture of the information machine, and the approach to analyze and extract the information in the network packets.

We propose a mechanism to detect network attack,based on the combination of the network environment information auto-apperceiving technology and the intrusion detection technology,and present annother mechanism of network flow transparent redirection based on OpenVPN and strategy routing.

In this paper, automaton network model and Agentbased modeling and simulation method are integrated, and a kind of Agentbased automation network model is put forward.

The development of computer information network, that has led mankind into a completely new information society, has brought revolutionay influence on people’s life-style and even on existing mode and has formed an information culture within the whole world.

This article from the computer system of information on the importance of the issue of security,focused on the impact of computer information network security factors and preventive measures.

Using ASP homepage programming language and the access database has realized the production process data net sharing,can reflect the production situation promptly,simultaneously the role of the computer network information in the production and life is also elaborated.
