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

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

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
