  3. Problem #1 • Consider an example application (e.g., from healthcare, defense, financial) • Specify some meaningful policies for this application that address confidentiality, privacy and trust

  4. Problem #2 • Consider an example application where there is a need for organizations to share data • Example: Defense: Army, Navy, Air Force • Healthcare: Doctor, Hospital, Insurance company • Give meaningful security policies illustrating the need for organizations share data and yet having to enforce the policies • Policies may include confidentiality, privacy and trust

  5. Problem #3 • Read the papers on RBAC, UCON and DCON listed in this unit • For an example application (or applications) specify policies for RBAC, UCON and DCON
