Briefly Describe Role-Based Access Control

Question

Examlex · Accepted Answer

The Answer is To determine what access privileges to assign, one model that should be used is role-based access control (RBAC). Instead of setting permissions for each user or group, permissions are assigned to a position ("role") and then users and other objects are assigned to that role. The users and objects inherit all of the permissions for the role. For example, instead of creating a user account Jeff.Butterfield and assigning privileges to that account, the role Comptroller can be created based on the privileges that position should have. Then the user can be assigned to that role. Individuals can hold multiple roles in RBAC.
The flexibility of RBAC makes it not only easier to establish permissions based on job classification but also facilitates enforcing those permissions. RBAC is considered a major step in keeping a WLAN secure.
