Unit 4: Access Control Mechanisms
Access control is a system that enables an authority to control access to areas and resources in a given physical facility or computer-based information system. In this unit, we will explore the access control mechanisms for user authorization. By the means of access control, appropriate authorization to information is provided to different entities in an organization. The common mechanisms include discretionary access control (DAC) and role-based access control (RBAC). We look into each of these in the context of their current usage in a typical enterprise.

Completing this unit should take you approximately 7 hours.
