Consider a computer system with three users: Alice, Bob, and Cyndy. Alice owns the file alicerc, and Bob and Cyndy can read it. Cyndy can read and write the file bobrc, which Bob owns, but Alice can only read it. Only Cyndy can read and write the file cyndyrc, which she owns. Assume that the owner of each of these files can execute it. Create the corresponding access control matrix. Cyndy gives Alice permission to read cyndyrc, and Alice removes Bob's ability to read alicerc. Show the new access control matrix
Consider a computer system with three users: Alice, Bob, and Cindy. Alice owns file X, and Bob and Cindy can read it. Bob owns file Y, and Cindy can read and write the file Y, but Alice can only read it. Cindy owns file Z, but neither Alice nor Bob can read or write it. If a user owns a file, he/she can also execute the file.
