Research on the Implementation Methods of Security Management of Distributed Database Application System

A method for implementing privileged management in security management based on role base access control model (RBAC2) is proposed. The idea is creating the users security information space and the security information space for the data base management system separately. The rule and method are given for implementing the mapping from the former onto the latter. The structure of the system for implementing the security management system in the client/server environment is also presented. The adoptability, easy usability and maintainability are primary characters of the method.
