Efficient Policy Analysis for Administrative Role Based Access Control By
Role Based Access Control (RBAC) has been widely used for restricting resource access to only authorized users. Administrative Role Based Access Control (ARBAC) specifies permissions for administrators to change RBAC policies. It is often difficult to fully understand the effect of an ARBAC policy by simple inspection, because sequences of changes by different administrators may interact in une...

Role Based Access Control (RBAC) has been widely used for restricting resource access to only authorized users. Administrative Role Based Access Control (ARBAC) specifies permissions for administrators to change RBAC policies. Due to complex interactions between changes made by different administrators, it is often difficult to comprehend the full effect of ARBAC policies by manual inspection a...
متن کاملPolicy Analysis for Administrative Role Based Access Control without Separate Administration
Role based access control (RBAC) is a widely used approach to access control with well-known advantages in managing authorization policies. This paper considers user-role reachability analysis of administrative role based access control (ARBAC), which defines administrative roles and specifies how members of each administrative role can change the RBAC policy. Most existing works on user-role r...
متن کاملIncremental Analysis of Evolving Administrative Role Based Access Control Policies
We consider the safety problem for Administrative RoleBased Access Control (ARBAC) policies, i.e. detecting whether sequences of administrative actions can result in policies by which a user can acquire permissions that may compromise some security goals. In particular, we are interested in sequences of safety problems generated by modifications (namely, adding/deleting an element to/from the s...
متن کاملPolicy Analysis for Self-administrated Role-Based Access Control
Current techniques for security analysis of administrative role-based access control (ARBAC) policies restrict themselves to the separate administration assumption that essentially separates administrative roles from regular ones. The naive algorithm of tracking all users is all that is known for the security analysis of ARBAC policies without separate administration, and the state space explos...
