Isolated From The Network-based Information Security Technology For Supply Chain Research

Supply Chain Management is coming to the age of network with the development of Internet, and more and more local area networks in many enterprises come to interlink with Internet. It is of high importance for the enterprises to ensure the information security under this condition. Information security has been a research hotspot in recent years, and it is difficult to get a satisfied solution. Different enterprise may have different approaches for its information security.At first, information security in Internet environment is analyzed in this paper, under the situation of an enterprise in JiangXi, in which the implement of Supply Chain Management Information System is carried out. Then based on some approaches in common use for resolving information security, and based on the fact of this enterprise, this paper from point of view of physical isolation brings a new way named "WengCheng" strategy to resolve this problem . This is a physical isolation strategy. The frame model of "WengCheng" strategy is expounded in this paper. And this paper mainly discusses how to realize network electron switch and components of data synchronization; those are two important parts of "WengCheng" strategy.Finally, the summary of this paper is given and some suggestions are made for further research on the topic.
