QUESTION 6

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 O3 to O2 that satisfy strict integrity?

A O3 to S1 to O2 B. None C. O3 to S2 to O2

QUESTION 8

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two security levels, L and H, where L <= H. The security levels associated with the objects and subjects is as follows: sl(O1) = L, sl(O2) = H, sl(O3) = L, sl(O4) = H, sl(S1) = L, sl(S2) = H. Select all the objects S1 can read that satisfy Bell-LaPadula security policy.

A. O4 . B. O2 C. O3 D.O1

QUESTION 9

Suppose we have four objects O1, O2, O3, and O4. Suppose we have two subjects S1 and S2. Finally, suppose we have two security levels, A and B, where A<= B. The security levels associated with the objects and subjects is as follows: sl(O1) = A, sl(O2) = B, sl(O3) =A, sl(O4) = B, sl(S1) = A, sl(S2) = B. Select all the objects S2 can read that satisfy Bell-LaPadula security policy.

A.O1 B.O2 C. O3 D.O4
