Automated Analysis of Permission-Based Security Using UMLsec


To guarantee the security of computer systems, it is necessary to define security permissions to restrict the access to the systems’ resources. These permissions enforce certain restrictions based on the workflows the system is designed for. It is not always easy to see if workflows and the design of the security permissions for the system fit together. We present research towards a tool which supports embedding security permissions in UML models and model-based security analysis by providing consistency checks. It also offers an automated analysis of underlying mechanisms for managing security-critical permissions using Prolog resp. automated theorem provers for first-order logic.
