What is Session

When organizations are collaborating, their access control models need to interoperate. However, nowadays in the industry, there are too many access control models variants and, most of times; the interoperability enforcement consumes an extra effort. In this context, this paper identifies the challenges towards how to design and enforce a meta-access control model to facilitate the interoperability between the different access control mechanisms available. The problem is posed using an ontological approach. Then, the challenges are explained using a descriptive explanation of the meta access control enforcement. The core issues addressed are: access models interoperability, standardization of storage for access data and provisioning of access models.
