Abstract
Nowadays access control has an important role in management of access to system resources Almost all of the current attribute based access control ABAC models do not meet all the operational needs in access decision while it absolutely will be an important role in the future access control models We believe that meeting the operational need in missions is necessary in ranking the attributes which are existed in the access control policies In this paper we propose a new approach that helps to enhance ABAC It creates the quantitative capability which we named it quantitative ABAC and is based on decision fusion We determine the attributes which have the most important role in the enterprises access management Then the experts consider and prioritize the attributes to determine which of attributes are more important than others In the other word we provide the weights as the importance of access control attributes based on decisionmakers’ viewpoints by utilizing ordered weighted averaging for the proposed prioritization As the result of this research it is possible that if there are some corrected values with high ranking among N parameters in attributes the permission may be granted The case study considerations show that decision fusion can be useful in solving some challenges of risk adaptable access control models This enables policymakers to manage and control the system resources more accurately and flexibility in integrated and complex systems The results of this study could be useful in integrated environments such as c4i systems
