The model that addresses the situation wherein one group is not
affected by another group using specific commands is called the:

A.
Information flow model

B.
Non-interference model

C.
Composition model

D.
Clark-Wilson model

Explanation:
In the non-interference model, security policy assertions are defined
in the abstract. The process of moving from the abstract to developing
conditions that can be applied to the transition functions that
operate on the objects is called unwinding.
* Answer “Information flow model” refers to the information flow model in which information is
categorized into classes, and rules define how information can flow between the classes. The
model can be defined as [O, P, S, T] where O is the set of
objects, P is the flow policy, S represents the valid states, and T represents the state transitions. The flow policy is usually implemented as
a lattice structure.
* The composition model, answer Composition model, investigates the resultant security
properties when subsystems are combined.
