Research And Implementation Of User Management Based On ASP Platform Security

ASP (Application Service Provider) platform provides an effective way to accelerate small and medium enterprises' information process. With the constant promotion of platform, increase of business users information (such as customer information, financial information, etc.), how to protect the security of users information has become a major obstacle for the development of ASP platform. Most ASP platform have taken relevant safety measures, but the research to platform safety only limited in physical security, network security and other surfaces, it makes security problem difficult to have a breakthrough. The thesis broke the limitations which emphasizes solving security problem by external factors, analyzed the ASP platform security issues from the point of user management, and stressed the importance of security strategy.Various factors which impact system security were analyzed from system architecture, technical support, business operations and other aspects. The user management's important effect for protecting platform security was discussed, demand was analyzed in emphasis, and a solution for user management was proposed from the point of users, a business model was set up; through analysis and comparison of the access control model, a role-based access control solution was established, the user-role-power mechanism was built, the access control model of user management was put forward, and the entire structure of user management system was designed; via researching user management object model design principles, the object model was projected from the perspective of design pattern, meanwhile, the sequence diagram of key business was designed , the database design rules were analysed in detail, and the concept model and logical model were projected; finally, the related technology and realization of system were introduced.
