    One way of viewing this is as a ladder where each rung of the ladder represents a different security level such as private, confidential, secret, and so on. The area between the rungs are identified as security boundaries.

    Data is assigned a label based on the security boundary where it's located. Users are also assigned labels to indicate what data they can access. When the labels match, access is granted.

    Further, there may be several different categories on the private level, such as private proprietary, private research, and private financial. Instead of using a single ladder, multiple ladders could be placed side-by-side. The rungs still represent different security levels, but now you have multiple categories on the same level with the different ladders. Each area within the rungs of each ladder is still assigned by a label.

    The term lattice seems to be a metaphor for a garden lattice or trellis used to guide climbing plants. A garden lattice has wooden slats perpendicular to each other creating multiple different areas similar to the areas between different rungs with multiple ladders side-by-side.
