Analysis And Design Of Database Security Access System

With the expansion of application scope of e-commerce, e-commerce network of crimes against the increasing. An external hacker to economic interests, social workers through a variety of techniques and means, steal the e-commerce website customer information. E-commerce information security cases published in recent years, insiders is the shortest board data security control, network crime cases in China in recent years the damage mostly shows the internal tendency of crime. In order to strengthen the security of database management inside enterprise electronic commerce, analyze and design the database security access system.The thesis firstly introduces the research background of database security access system, the problems need to be solved are reviewed, discussed the research significance and importance of the project, describes the system development method and related technology; the thesis puts forward the design goals of the system, the system carried out a detailed needs analysis, including business requirements, functional requirements, data requirements and non-functional requirements, business process diagram, use case diagram and class diagram of the concept of the system are given, for the use case description; in the design of the system, has carried on the system design and the module design, including the Department of management, user management, resource management, account management, virtual node management, application management, authorization management, single sign on, file management, audit management function module, the structure chart of the function module design is given (the package diagram, class diagram, sequence diagram)(co mapping) and processing flow chart, elaborates the design content, and use the entity class diagram, E-R diagram and database table structure of the database is designed in detail the thesis finally; the contents of the study are summarized, elaborated the main work of the thesis, points out the shortcomings of the, and the further work is prospected.Based on the framework of B/S database security access system, oriented to security personnel of e-commerce enterprise data management, to provide for the Department, users, resources, accounts, virtual node, application, authorization, and audit log file management functions, and establish a standardized interface, the user client, virtual node server component call related information to realize virtual application start with the single sign on database, and realize the data transfer are enclosed in a virtual environment, data file operations are recorded, effectively prevent the internal electronic business enterprise employee information theft.
