Policy Enforcement for Secure and Trustworthy Data Sharing in Multi-domain Infrastructures

The push for data sharing and data processing across organisational boundaries creates challenges at many levels of the software stack. Data sharing and processing rely on the participating parties agreeing on the permitted operations and expressing them into actionable contracts and policies. Converting these contracts and policies into an operational infrastructure is still a matter of research and therefore begs the question of how should the software stack and infrastructure look like? What are the main building blocks of such an architecture? In this paper, we investigate the architecture of a multi-domain distributed architecture for policy driven application. The architecture spans components from auditing policies to managing network connections.
