CRABAC: Combined Role-Attribute Based Access Control Model

Abstract

Access control is one of the techniques to provide accessibility, flexibility and control over the cloud resources. The traditional access control model is no longer sufficient to provide protection of data. Due to the rising data breaches, it is important to evolve our data security mechanisms. Therefore, it is better to combine several techniques to bring out the most efficient technique. Thus, this paper introduces custom access control model where Role- Based Access Control (RBAC) model and Attribute-Based Access Control (ABAC) model is combined to give a single hybrid model. This technique brings out the best qualities of both models. It provides both flexibility and dynamicity. The assignment of attributes provides better security.
