Security and Access Control Evaluation for Cloud Data Centers
Cloud computing is a computing paradigm that enables highly scalable services to be consumed over the Internet on a shared basis. Cloud service providers place data in data centers which is distributed as shared data to the users. Users' data are usually processed remotely in unknown machines that users do not ownership. Centralized monitoring applications are not suitable in the cloud environment and hence data access is provided on a shared basis by cloud service providers. These shared data values are monitored by different cloud auditing schemes. Cloud Information Accountability is an efficient framework for this auditing. This combines the data aspects of access control, usage control and authentication.
