Towards Managed Role Explosion

Content Provider	ACM Digital Library
Author	Knight, Scott Elliott, Aaron
Abstract	Role-based access control (RBAC) is a popular framework for securing information systems in medium to large organizations with hundreds or thousands of employees. However, very few descriptions of existing RBAC systems can be found in the literature. In this paper, we challenge the belief, notion or sense that the number of subjects far exceeds the roles found in enterprise systems. First, we analyze the RBAC system found at ACME University, comparing it to a recently introduced fragment of RBAC called bi-sorted role-based access control (RBÄC). Then we investigate how ACME performs access management, using our new hierarchical graphing model to better visualize the subject-permission mappings. Next, we present our results and introduce a new role-centric methodology for dynamically constraining access to information. Finally, we describe how organizational scalability is enhanced at ACME University by decoupling subject and permission management at the expense of managed role explosion.
