3: Your focus is now on ensuring integrity instead of confidentiality. In other words, all we care about is who can modify an object (not which object is disclosed, which was the focus for ensuring confidentiality). The hierarchy below shows a lattice in the context of a military. In this lattice, the dominates relation is equivalent to information flow, which in turn is synonymous to flow (up/down) of military information between different ranks of officials (e.g., sergeants take order from generals; generals give orders to sergeants). Note: the arrows do not carry a special meaning in the lattice below. Sergeant Dept-1 Soldier Dept-1 General Sergeant Dept-2 Soldier Dept-2 Sergeant Dept-3 Soldier Dept-3 Question: Using this scenario and the lattice above, explain and justify whether the simple and star properties in the Biba model are satisfied or not.
