Explanation

Mandatory Access Control (MAC) is a system-enforced access control model where the operating system or database assigns classification labels to data and to users. Access decisions are made by the system-not by data owners-based on these labels. In a data warehouse context, MAC enforces rules that hide (mask) data classified above a user's clearance level, presenting only the subset of data they are authorized to see within the larger database. This is distinct from discretionary access control (DAC), where owners decide access, and from role-based access control (RBAC), which grants access by role rather than by classification label.
