Represent the ownerships and permissions shown in this UNIX directory listing as a protection matrix. (Note: asw is a member of two groups: users and devel; gmw is a member only of users.) Treat each of the two users and two groups as a domain, so that the matrix has four rows (one per domain) and four columns (one per file). - rw- r- - r- - 2 gmw users 908 May 26 16:45 PPP- Notes - rwx r- x r- x 1 asw dev el 432 May 13 12:35 prog1 - rw- rw- - - - 1 asw users 50094 May 30 17:51 project.t - rw- r- - - - - 1 asw dev el 13124 May 31 14:30 splash.gif
