Using UML to Visualize Role-Based Access Control Constraints
Overview Organizations use Role-Based Access Control (RBAC) to protect information resources from unauthorized access. The paper proposes an approach, based on the Unified Modeling Language (UML), that shows how RBAC policies can be systematically incorporated into an application design. The paper considers an RBAC model to be a pattern which the paper expresses using UML diagram templates; RBAC policies for an application conforming to this model can be generated by instantiating these templates with values obtained from the application. The constraints of the RBAC model are expressed using the Object Constraint Language (OCL). OCL constraints, based on first-order logic, are difficult to understand. To alleviate this problem, the paper shows how violation of such constraints can be visually represented using object diagram templates.
