Abstract: Access control is the process of maintaining every user request and allow to access the resources and data manage by a system. It also decide whether to grant or denied the requester. The decision of access control is depend on the rules and regulation applied by security policies. Different access control policies corresponds to the different criteria such as what is allowed and what is not allowed with defining security means. The two main challenging problems of access control policies are: inconsistencies and incompleteness. To detect and resolve such problems, various access control policy validation techniques are proposed by the researchers. In this survey we identify the basic concepts of access control policies and different security requirements. We studied and compare various policies and models based on their advantages and limitations.
