What does the 'lattice-based' model in access controls primarily compartmentalize?

The 'lattice-based' model in access controls primarily focuses on incorporating multiple levels of security classifications and the relationships between them, which are represented by classification labels. This model is often used in environments where there is a need to manage access based on the sensitivity of information, allowing users with specific clearance levels to access data marked with corresponding labels.

In the lattice-based model, the hierarchical structure of security levels creates a framework where access decisions are made based on the clearance level of the user and the classification level of the data. The concept of lattice refers to a structure where users can access certain data only if they have sufficient clearance that meets or exceeds the classification label associated with that data.

In scenarios that utilize this model, it becomes crucial to define and enforce the relationships between users and the classification labels that govern access rights. This ensures that individuals can only access information that they are authorized to see, maintaining a high level of data security and integrity. The lattice model thus directly correlates with how classification labels influence access controls.
