RBAC centers on predefined roles that reflect job functions such as Accountant, Server Administrator, or HR Clerk. Each role is granted the specific permissions needed to perform its associated duties. Users do not receive rights directly; instead, they gain them by being placed into one or more roles. Doing so simplifies administration, especially when people join, leave, or change jobs. The other options describe different access control approaches: directly assigning rights to individual users corresponds to discretionary access control (DAC); matching user clearance with data classification is characteristic of mandatory access control (MAC); and making decisions at login based on many attributes (user, resource, environment) is attribute-based access control (ABAC).
