Abstract

In recent years, Role Based Access Control (RBAC) has emerged as the most popular access control mechanism, especially for commercial applications. In RBAC, permissions are assigned to roles, which are then assigned to users. The key to the effectiveness of RBAC is the underlying role set that is used. The process of identifying an appropriate set of roles that optimally meets the organizational requirements is called role mining. One of the most useful constraints that can be expressed in RBAC is Separation of Duty (SoD). SoD constraints allow organizations to put a restriction on the minimum number of users required to complete a critical task. However, existing role mining algorithms do not handle SoD constraints and cannot be easily extended to incorporate SoD constraints. In this paper, we consider the problem of role mining when SoD constraints are present. We develop three alternative approaches that can be applied either during or after role mining. We evaluate the performance of all three approaches on several real world data sets and demonstrate their effectiveness.
