A security administrator needs to configure remote access to a file share so it can only be accessed between the hours of 9:00am and 5:00 pm. Files in the share can only be accessed by members of the same department as the data owner. Users should only be able to create files with approved extensions, which may differ by department. Which of the following access controls would be the MOST appropriate for this situation?

• RBAC

• MAC

• ABAC

• DAC
