Role-Based Access Control (RBAC) is an approach to restricting system access to authorized users.

Role Based Access Control (RBAC), a technical means for controlling access to computer resources. In computer systems security, role-based access control (RBAC) is an approach to restricting system access to authorized users. It is a newer alternative approach to mandatory access control (MAC) and discretionary access control (DAC). RBAC is sometimes referred to as role based security. RBAC is a policy neutral and flexible access control technology sufficiently powerful to simulate DAC and MAC. Conversely, MAC can simulate RBAC if the role graph is restricted to a tree rather than a partially ordered set.

Role Management allows identity and security administrators to grant privileges (or entitlements) using a layer of abstraction that allows for easier management. By using roles to administer rights, we can cut down significantly on the number of transactions needed to initially assign those rights as well as to maintain, modify and remove them.
