Which access control model ties permissions to roles, a pattern often used for standard TA access?

• A. RBAC
• B. ABAC
• C. DAC
• D. MAC

Answer: (A)

Tying permissions to roles is the hallmark of role-based access control. In this model, permissions are assigned to roles rather than to individual users, and users gain access by being granted one or more roles. This setup mirrors how many organizations operate, especially for standard TA access, because job functions map naturally to roles. Administrators can manage access by adding or removing roles rather than tweaking permissions for each person, which makes administration scalable and helps enforce least privilege.

Other approaches work differently: attributes-based access control grants access based on user, resource, and environmental attributes and policies; discretionary access control relies on the owner of an object to grant permissions; mandatory access control uses fixed security labels and clearances.
