Cloud-Based Access Control Framework for Effective Role Provisioning in Business Application

In the evolution of social networks and big data, secure information sharing is a crucial task. When information is shared between the user and the organization admin, security plays a key role in any business organization in terms of privacy. Though many fruitful solutions prevail to protect the data integrity and privacy, there is a huge space for novel data protection schemes where a large set of data are involved. In this article, the Cloud-Based Access Control (C-BAC) framework is proposed which can fit in any business organization application. In this C-BAC, Policy Enforcement Point (PEP) is used to avoid unwanted information sharing with the neighboring employee. C-BAC framework with RSA provides security, based on the number of employees with the data handled by the particular employee, better than the existing access control framework with asymmetric encryption standard (AES) and Rivest–Shamir–Adleman (RSA) in terms of individual information handling.

Traditionally, access control mechanisms have been hard-coded into application components. Such approach is error-prone, mixing business logic with access control concerns, and affecting the flexibility of security policies, as is the case with IFRN SUAP Django-based system. The externalization of access control rules allows their decoupling from business logic, through the use of authorization servers where access control policies are stored and queried for computing access decisions. In this context, this paper presents an approach that allows a Django Web application to delegate access control decisions to an external authorization server. The approach has been integrated into an enterprise level system, which has been used for experimentation. The results obtained indicate a negligible overhead, while allowing the modification of access control policies without interrupting the system.
