Quotes

In this model [Multilevel Security Pattern - Ed.] users and data are assigned classifications or clearances. Classifications include levels (top secret, secret,…), and compartments (engDept, marketingDept,…). For confidentiality access of users to data is based on rules defined by the Bell- LaPadula model, while for integrity the rules are defined by Biba’s model [Sum97]. Figure 5 shows its basic structure.

In the military and government sectors, the individual set elements (that is A and B) are known as categories; the security classes (that is, sets of categories) are known as compartments.
