The modification of roles in hierarchy RBAC is very difficult. With the analysis, it is clear that the difficulty of roles' modi- fication comes from the hierarchy constructing on the permission inheritance. Any change of permission will shock the hierarchy. For the sake of the convenience of roles' modification with a firm hierarchy, a hierarchy RBAC model is proposed based on separation of duty. This modelseparates the role on the basis of abstract versus concrete and acquires theability of the convenience of roles' modification with a firm hierarchy.
