Answer these 3 question

QUESTION 3

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two integrity levels, L and H, where L < = H The integrity levels associated with the objects and subjects is as follows: il(O1) = L, il(O2) = H, il(O3) = L, il(O4) = H, il(S1) = L, il(S2) = H. Select all the objects S1 can modify that satisfy strict integrity.

A.O1     B.O2    C. O3    D.O4

QUESTION 4

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two integrity levels, L and H, where L <= H . The integrity levels associated with the objects and subjects is as follows: il(O1) = L, il(O2) = H, il(O3) =L, il(O4) = H, il(S1) = L, il(S2) = H. Select all the objects S2 can modify that satisfy strict integrity.

A.O1     B.O2    C. O3    D.O4

QUESTION 5

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two integrity levels, L and H, where L <= H. The integrity levels associated with the objects and subjects is as follows: il(O1) = L, il(O2) = H, il(O3) = L, il(O4) = H, il(S1) = L, il(S2) = H. What transfer path exists from O4 to O1 that satisfy strict integrity?

A. None B. O4 to S1 to O1 C. O4 to S2 to O1

Explanation / Answer

Question:3

Option:A.&C

Explantion:

With "The Windows integrity levels are ordered so that a lower value indicates less trustworthiness, and a higher value indicates greater trustworthiness. A lower-level subject cannot modify a higher-level object." this windows policy, Subject S1 cannot modify O2 and O4...........................
