Abstract

The principle of least privilege is a well known design principle to which access control models and systems should adhere. In the context of role-based access control, the principle of least privilege can be implemented through the use of sessions. In this paper, we first define a family of simple role-based models that provide support for multiple hierarchies and temporal constraints. We then investigate a question related to sessions in each of these models: the inter-domain role mapping problem. The question has previously been defined and analyzed in the context of a particular role-based model. We redefine the question and analyze it in the context of a number of different role-based models.
