Research On The Architecture And Security Baseline Of Enterprise Information System

In the process of enterprise information system construction,enterprise information system architecture(EISA)is the main framework of the information system design.Regardless of information technology,network technology,computer software and hardware technology,or business procedures,management methods,resource integration,corporate culture and strategic planning,this structure has been involved,is the information system designers to identify the needs of the enterprise.EISAis a prop for information system designers to identify enterprise needs.Developing EISA is the most important subject for the enterprise information system designers.With the development of enterprise informatization,information security has become a threat to the enterprise survival.The information security and EISA are researched synchronously,trying to solve the waste of investment due to the disconnection of security design and overall design,and the key information resource is not protected specially.Themain researchwork ofthispaperis as follows:(1)Through the analysis of the elements of the enterprise information system,the connection mode,the basicfunction,the design standard,the hierarchical divisionand the information flow,the three-dimensional system structure is designed.In particular,the technical system architecture provides the system design should be in accordance with the technical specifications and standards;support system architecture to define the system elements and the elements of the connection mode;operation system architecture provides a system of business and information program.The system architecture of enterprise information system is designed by this paper,andprovides a theoretical basis andframework for the overall design of theinformationsystem.(2)Discussed the logical structure of information system security framework.The main security problems in the enterprise information system are analyzed.And relying on the system architecture,the security modelofenterpriseinformationsystem isdesigned.(3)This paper discusses the rationality of information system security baseline.The database system,network environment and the operating system are analyzed,and the national security standard is considered.The security baseline are configured on the basis of securitymodel.
