With the Lattice Based Access Control model, a security class is also called a:

A.
Control factor

B.
Security label

C.
Mandatory number

D.
Serial ID

Explanation:
The Lattice Based Access Control model was developed to deal mainly with information flow in
computer systems. Information flow is clearly central to confidentiality but to some extent it also
applies to integrity. The basic work in this area was done around 1970 and was driven mostly by the
defense sector. Information flow in computer systems is concerned with flow from one security class
(also called security label) to another.
These controls are applied to objects. An object is a container of information, and an object can be a
directory or file.
