In many systems access control takes the form of a simple password mechanism, but many require more sophisticated and complex control. An employee can access objects and execute operations only if their role in the system has relevant permissions. For maximum security, a Mandatory Access Control (MAC) system would be best. But users with the privileges can share them with users without the privileges. Fortunately, there are diverse systems that can handle just about any access-related security task. Role-based access depends heavily on users being logged into a particular network or application so that their credentials can be verified. There are three RBAC-A approaches that handle relationships between roles and attributes: In addition, theres a method called next generation access control (NGAC) developed by NIST.

For example, when a person views his bank account information online, he must first enter in a specific username and password. In short, if a user has access to an area, they have total control.
