The Research And Implementation Of Information System's Security Mechanism Based On Domino/Notes

21th century is an information century, information became an important stratagem resource. With the developing of the information technology, information system applied into politics , economy , military , etc, and influence run of government organization and enterprise, and people's life. As long as any break appears in computer information system, it makes a huge impact on whole society, Therefore, ensure information system's security has became a society problem And hot research project of computer science. There is an important, direct and realistic significance in research information system security.Lotus Domino/Notes is an enterprise level information structure, which's dimension can be regulated, and it is also a strong C/S application development environment between different platforms. With our country information's course speed up, many industry and department constructed information system, and many information system selected Domino/Notes as their work platforms. We selected Lotus Domino/Notes as the development platform for the information system in the process of the boiler tension test and research institute of Hubei information system's construction. In the process of system security construction, how to use develope platform's security mechanism to intensify system's security is this paper's emphasis and difficulty.This paper analyzed the information system security deeply, included base need and concept of information system security, origin of security problem and security strategy. It studied the security technology related to information system, included cryptogram technology, Fire Wall technology, database security technology, digital signature, authentic technology and VPN technology.It studied the security mechanism of Domino/Notes and its technology of across authentication, and its digital signature and analyzed its multi-layer safety model.Based on these research, This paper analyzed the information system security deeply on the background of the boiler tension test and research institute of Hubei information system, analyzed the security requirements and security object deeply.integrated with Domino/Notes strong security mechanism, put forward and realized the model of information system's security mechanism. This security mechanism of information system applied the multi-layer to realize the system's security, which can be divided into physical layer, network layer, system layer, application layer, manage layer. Integrated with Domino/Notes, used arrangement nominate structure , identity authentication , database access control , information encryption , digital signature and digital sign badge etc, emphasized the security of application layer. It made information system, from access system to operate database and sign badge, all these things under security control.
