Using a directed graph to represent each subject and each object by a node, depict the protection state shown in the discretionary access control (DAC) model described in the textbooki. An entity which is both subject and object is represented by a single node. A directed line from a subject to object indicates an access right. A label on that link defines the type of access right. Draw a directed graph that corresponds to the access matrix of figure below. Draw on MS Word. ORRIS Files $ Sahjects $ $ Duke D. w + SUBJECTS w 1
