Review and Analysis of Access Control Mechanism for Cloud Data Centres

Abstract

Nowadays the cloud is very useful for providing many IT services. These services are delivered over the internet and accessed globally with the help of internet. The cloud service provider ensures flexibility in provisioning and scaling of resources. The cloud services are completely managed by cloud service provider (CSP), which ensures the end to end availability, reliability and security of the cloud resources. The exponential growth of cloud services has provided many opportunities but has also perplexed severe security concerns. The popularity of cloud service-based applications is rapidly increasing due to which many security and legal issues are arising. In this paper, we reviewed the existing access control method and framework for cloud data centres. The different concept of reputation and attribute-based access control system has been analyzed. This review of access control approach is helpful in designing of new access control framework and to mitigate the challenges in security concerns.
