CYPR 7443 Module 6 Assignment 1. Consider that GeoGold maintains the following mission terrain data as objects: Asia data, Europe data, South America data, Australia data, and North America data. There are five subjects: Abe, Bob, Cal, Paul, and John. The access control matrix, A, with no permissions, is as follows: A. Perform the following commands on the above matrix: Use the lecture on the Access Control Matrix to craft the answer. Your results should be cumulative. i. Assign the right "read" to the Abe and john over North America Data ii. Assign the rights "read" and "write" to the Bob over Asia and Europe Data iii. Assign the right "Own" to the Paul over Europe Data iv. Add Alice as a new subject. v. Destroy Cal as subject vi. Destroy South America Data as the object vii. Remove the rights "write" to the Bob over Europe Data viii. Assign the right "Copy" to the Paul over Europe Data ix. Assign the right "read", "write", "own" and "copy" to the Abe over Australia Data x. Assign the right "read" to the Alice over all remaining data objects. B. Write the following two commands and show the protection state changes from the resulting ACM in 1.A after executing the command. Start with the blank ACM in 1.A for each of i and ii below. Use the lecture in on the Access Control Matrix to craft the answer. i. Paul gives Alice "write" permissions over Europe data, if Paul has "own" and "copy" rights over Europe data, and Alice already has "read" permissions over Europe data. ii. Abe removes the "read" permission from Alice over Australia data, if Abe has "own" rights over Australia data
