Explanation:
Mandatory controls are access controls that are based on a policy that the user, and
more importantly the processes running with that user’s privileges, is not allowed to
violate. An example of this is “Top Secret” data is configured so that regardless of
what the user does, the data cannot be transmitted to someone who does not have “Top
Secret” status. Thus no “trojan horse” program could ever do what the user is not
allowed to do anyway. The restrictions of mandatory controls are (at least in normal
mode) also applied to the user who in a discretionary system would be “root”, or the
superuser.
