Abstract�� Role based access control was being paid more and more attention as a security mechanism. Traditional access control policies, including discretionary access control (DAC) as well as mandatory access control (MAC), were first briefly introduced. An access control model based on RBAC2 was provided, which not only inherited the advantage of RBAC2, but also extended the ability of modifying individual permissions. An example application of the model is presented as a proof of its availability. The distributed management for permissions was discussed.
Keywords�� management information system   resources   matrices   discretionary access control   Mandatory access control   role
