Abstract: Access control is a security process, which work as a facilitator between every initiated resource and access request to determine whether the system allows or deny the request. Access control is important for preventing theft of data and resources for ensuring that they are safe and well kept at all times. Thus in rapidly growing IT environment, unauthorized access becomes a form of threat. An organization or industry may possess a wealth of critical resources, but those resources are not at all available to each and every employee, customer or partner. Industries and organizations must implement access control mechanism to ensure that each user whether inside or outside of an organization had only necessary access to the required resources. We discuss here various architectures, policies and models for access control, which are trying to illustrate why they are so much crucial for any organizations. In this paper we are providing an elaborative approach to enhance access control architecture. Also we discuss some key aspect for designing access control architecture.
