Consider an access control matrix with N subjects and M objects that are into subjects.

Consider an access control matrix with N subjects and M objects that are into subjects. Assume that, the number of assignable permissions per (subject, object) pair is a maximum set of {R,W,X,W} that stands for read, write, execute and own respectively.• What is the maximum length of the access control list creatable for this access control matrix?• What is the maximum number of privilege lists that are creatable from this access control list?• Assume that there are G many groups (where G << 2N) that may that are listed as subjects in the access control lists where every subject belongs to at least one group, but a subject may belong to at most 4 groups. What is the maximum and minimum size of the access control list creatable by doing so?• What is the longest access control list assigned to a group?
