Research on information security access model and its implementation strategies

More and more the engineering of complex data-based systems calls for infrastructural support for security issues integrated with services for the management of system organization. With taking Role-Based Access Control theory as reference architecture and considering data security as the research core, the paper imports user permission and analyses the communication mechanism of combination between Flex and C#.Net in detail. Then, under the application of B/S, it introduces the design model of security access management, which is accomplished by software programming with layered architecture. In addition, it presents the achieved technologies and methods to guarantee the data security by the processing program of verifying, authorization, database security, the prevention of unauthorized access and other methods. Practice shows that design and methods applied in this paper make convenient for system expansion and maintenance, and improves system scalability, management flexibility and data security.
