A flexible fine-grained dynamic access control approach for cloud computing environment
2021
Overview
As a pioneering surge of ICT technologies, offering computing resources on-demand, the exceptional evolution of Cloud computing has not gone unnoticed by the IT world. At the same time, security stands as a most prior concern for this new progressive computing capability of on-demand services over the Internet. Hence, access control substantiates one of the fundamental conditions to fortify the information and Cloud system against illegitimate access among all the security requirements of Cloud computing. Although diverse access control models have been proposed and implemented for the Cloud computing paradigm, the models may fail to accomplish the dynamic and scalable requirements of the Cloud system adequately. Therefore, we propose a dynamic authorization system for a Cloud computing environment that employs the concept of role, task, and trustworthiness of the user. In this paper, a framework has been proposed that offers characteristics of both passive and active access control along with the trusted computing, thereby, blending the model into a more fine-grained and dynamic for the Cloud computing environment. Subsequently, the implementation of the propounded scheme is reported to provide the proof-of-concept. Additionally, the evaluation and use case scenario of the propounded system has been carried out to proclaim its effectiveness over other conventional models.
