Security access control research trends

Information security policy is a critical property in any organization. For systems, the security policy addresses constraints on access by external systems and adversaries including programs and access to data by people. A continuous research effort is done throughout security policy aspects, such as policy procedures, documentation, policy enforcement, and administration. In this paper, we explore the research trends in an important component of security policies, which is access control. We survey the different modes of access controls, and identify the open research areas associated with them.
