Title: Access Control and Obligations in the Category-Based Metamodel: A Rewrite-Based Semantics
Authors: Sandra Alves
Issue Date: 2015
Abstract: We define an extension of the category-based access control (CBAC) metamodel to accommodate a general notion of obligation. Since most of the well-known access control models are instances of the CBAC metamodel, we obtain a framework for the study of the interaction between authorisation and obligation, such that properties may be proven of the metamodel that apply to all instances of it. In particular, the extended CBAC metamodel allows security administrators to check whether a policy combining authorisations and obligations is consistent.
