Study On SSE's Extranet Security Establishment Measures

As the swift development of computer international mutual network, there is a misapprehension to the electronic commerce, which thinks that the essential of the electronic commerce is to reduce the number of exchange agencies. But in fact, under the macroscopical environment of the electronic commerce, the exchange agency couldn't disappear. As the development of its function, the complexity of its structure, the mightiness of its performance, the enterprise and consumer will depend more on it. The functional orientation of Shanghai Shipping Exchange (SSE) and the effect that it exerts in practice decide that it will be the exchange agency in the electronic commerce time as the Internet dissemination.Extranet is a system that applies the constitutional technology of Internet to the interspaces of enterprises. It is a mutual cooperative network by which the enterprise and its client or other enterprises obtain their common goals. To construct Extranet's network establishment of SSE will has an important and far-reaching meaning. However, there are so many enterprises about harbor, water transportation, freight agent in the exchange of SSE. So when two or several enterprises are connected with Extranet, the safe problems faced every enterprise will increase. Safe leak may form diversified tangible and intangible lose. But we know, through the investigation to the safe establishment of SSE' s network establishment, that they are deficient. Because of the weightiness about SSE' s network safe establishment, it is exigent to establish SSE' s Extranet security. The paper hammers at the study of SSE' s Extranet security establishment measures.As people always think that safe establishments are commonly the responsibility of technology personnel, so manager know little about network safe measure. However, to set down a successfully safe establishment measure is not easy and it isn't the system administrators' business as people generally think. It need the crew's cooperation, especially manage. The paper try to combine the knowledge about manage and computer network security, to put forward the Extranet's safe establishment measure which can be accepted by the manager and accord the enterprise's whole and long-term developing layout. Because of theSSE' s particularity, the paper study the Extranet's safe establishment measures through drawing Extranet's safe plan and actualizing safe pilot.The paper analyses the Extranet's safe plan through weightiness, the factors that should be considered, goal establishment. The keystone is the safe technology that is used in data confidentiality, data integrality, data authentication. But because the plan and goal isn't perfect and the actualizing procedure is dynamic, it will not agree with the demand of plan and goal in practice. Therefore, the keystone is how the SSE actualizes control to consummate plan and goal.
