Abstract
In recent years, Attribute-Based Access Control (ABAC) has emerged as the desired access control model in scenarios involving sharing of resources across multiple domains. This necessitates organizations using traditional access control models to use ABAC. However, ab initio deployment of ABAC is both cost and time intensive. In this paper, we present ABACaaS - a cloud service that enables any organization to integrate ABAC into their own environment irrespective of the platform they operate in. We show both SaaS as well as PaaS instances of ABACaaS along with results on its performance.
