What security model is dependant on security labels?

A.
Discretionary access control

B.
Label-based access control

C.
Mandatory access control

D.
Non-discretionary access control

Explanation:
With mandatory controls, only administrators and not owners of resources may
make decisions that bear on or derive from policy. Only an administrator may change the category
of a resource, and no one may grant a right of access that is explicitly forbidden in the access
control policy. This kind of access control method is based on Security labels. It is important to
note that mandatory controls are prohibitive (i.e., all that is not expressly permitted is forbidden).
