In a Mandatory Access Control (MAC) model, security labels are assigned to both subjects (users, processes) and objects (files, resources). Subjects receive clearance labels (e.g., Top Secret, Secret), and objects receive classification labels. Access is granted only when the subject's label meets or exceeds the object's label.
