Abstract
It has been argued that security perspectives, of which access control is one, should be taken into account as early as possible in the software development process. Towards that goal, we present in this paper a tool supporting our modelling approach to specify and verify access control in accordance to the NIST standard Role-Based Access Control (RBAC). RBAC is centred on mapping users to their roles in an organisation, to make access control permissions easier to set and maintain.
Our modelling approach uses only standard UML mechanisms, like metamodels and OCL constraints, and improves on existing approaches in various ways: designers don’t have to learn new languages or adopt new tools or methodologies; user-role and role-permission assignments can be specified separately to be reused across models; access control is specified over class and activity diagrams, including ‘anti-scenarios’; access control is automatically verified. The tool is built on top of an existing modelling IDE and allows for automatic verification of models according to our RBAC modelling approach, while providing users with the ability to easily identify and correct errors in the model when they are detected.
