Final answer:
An administrator uses role-based access control (RBAC) to assign permissions and rights to a collection of user accounts, simplifying the process by associating users with roles according to their job functions, and enhancing control over access in the system.
Step-by-step explanation:
An administrator uses a method that assigns permissions and rights to a collection of user accounts. This method is known as role-based access control (RBAC). In RBAC, user accounts are assigned roles, and these roles are tied to specific permissions that control the level of access and actions the users can perform within a system or network. It simplifies the process of managing user permissions by associating users with roles based on their job functions and responsibilities rather than assigning permissions to individual users, which can be more labor-intensive and error-prone.
For example, in a company, employees in the HR department might be assigned to a 'HR' role, which grants them access to staff records and the ability to update employee details, while the IT department staff might have a 'System Administrator' role that allows them to manage user accounts and maintain system integrity. By using RBAC, the control of access is streamlined, making it easier for the administrator to manage user rights and permissions effectively.
