What is Role-Based Security?

Role-Based Security (RBS) is a system by which users are granted permissions implicitly by being assigned various roles. A role is a collection of permissions, or access points. Each permission indicates an ability to perform some action. The permission might be something as vague as Administration or as detailed as Create New Orders. Each role is granted a list of permissions, and the permissions inherited by the user are the list of all permissions granted to all of the roles to which the user belongs.
