Label Ranges

The security administrator defines label ranges and label sets to enforce mandatory access control (MAC) policy. A label range is a set of labels that is bounded at the upper end by a clearance or a limit and at the lower end by a minimum label. A label limit is the upper bound of a label range. A label set contains one or more discrete labels that might be disjoint from one another. Labels in a label set do not dominate one another.
