Distributed Middleware Enforcement of Event Flow Security Policy
Source: University of Cambridge
Distributed, event-driven applications that process sensitive user data and involve multiple organisational domains must comply with complex security requirements. Ideally, developers want to express security policy for such applications in data-centric terms, controlling the flow of information throughout the system. Current middleware does not support the specification of such end-to-end security policy and lacks uniform mechanisms for enforcement. The authors describe DEFCon-Policy, a middleware that enforces security policy in multi-domain, event-driven applications. Event flow policy is expressed in a high-level language that specifies permitted flows between distributed software components.
