Data and Applications Security Developments and Directions

This assignment delves into access control policies and their significance in data security, particularly in applications such as healthcare, defense, and finance. It includes a detailed examination of Role-Based Access Control (RBAC), Usage Control (UCON), and Dissemination Control (DCON) frameworks. By analyzing meaningful policies that address confidentiality, privacy, and trust, the assignment illustrates how organizations can share data while enforcing essential security measures. The findings aim to contribute insights into effective data-sharing practices across different sectors.

  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
