What are the three basic elements of RBAC in AIX?

Groups and Access are standard Unix discretionary access control concepts, and Keys is not a defined component of the AIX RBAC architecture.

Keys is not a component of AIX RBAC - while Privileges exist in the RBAC model, this combination does not accurately represent the three foundational elements.

KeyStore is an AIX cryptographic key management facility unrelated to RBAC - Users and Groups are general AIX concepts that interact with RBAC but are not its defining structural elements.

In AIX RBAC, Authorizations define the specific operations a user is permitted to invoke, Privileges grant the ability to execute commands with elevated rights beyond normal user capabilities, and Roles are named collections of authorizations and privileges assigned to users or groups. These three elements are interdependent and form the complete RBAC model that AIX uses to delegate administrative tasks securely.
