"Need to know" is correct. In Dedicated Security Mode the subject must have "need
to know" for ALL the information contained within the system. With System High Security Mode
the subject must have "need to know" for only the information they are trying to access.
The following answers are incorrect:
"The clearance required"
It is incorrect because all the data on the system require the same clearance, but this is the same
for both systems.
"Object classification"
It is incorrect because all the data on the system require the same classification level. Although
the need-to-know is part of the object's label this is not the best answer.
"Subjects cannot access all objects"
It is incorrect because the more correct answer is need to know. Although because of need to
know, certain subjects cannot access all objects, the best answer is need to know.
