Attribute-based access control (ABAC) is a promising alternative to traditional models of access control (i.e. discretionary access control (DAC), mandatory access control (MAC) and role-based access control (RBAC)) that is drawing attention in both recent academic literature and industry application. However, formalization of a foundational model of ABAC and large scale adoption are still lack...
