Researchers have proposed severalRBAC models, which include the famous RBAC96 model. However, these frameworks are sometimes hard for sys-tem developers to understand because the models defined are too abstract or focus on application-oriented solutions.In this paper, a new model (OSRBAC)is discussed, which is the improved model to RBAC3 model in RBAC96 modelfamily. Compared with RBAC3 model, OSRBAC model is more concrete and easilier to understand. At the end, thispaper describes the implementation of OSRBAC model in RedFlag Secure Operating System(RFSOS).展开更多
