Final answer:
RBAC permissions are assigned to a)roles.
Step-by-step explanation:
When using Role Based Access Control (RBAC), permissions are assigned to roles. RBAC is a security model that defines access rights based on the roles that individuals have within an organization.
For example, in a company, there might be roles such as 'admin', 'manager', and 'employee'. Each role will have different permissions associated with it, determining what actions they can perform and what resources they can access.
By assigning permissions to roles, it becomes easier to manage access control and maintain security within an organization.
