Abstract

The scalability properties of event-based communication paradigms make them suitable for building large-scale distributed systems. For effective management at the application level, such systems often comprise multiple administrative domains, although their underlying communication infrastructure can be shared. Examples of such systems include those required by government and public bodies for domains such as healthcare, police, transport and environmental monitoring. We investigate how to build security into these systems. We outline point-to-point and publish/subscribe event-based communication, and examine security implications in each. Publish/subscribe decouples communicating entities. This allows for efficient event dissemination, however it makes controlling data visibility more difficult. Some data is sensitive and must be protected for personal and legal reasons. Large pub/sub systems distribute events using intermediate broker nodes. Some brokers may not be fully trusted. We discuss how selective encryption can effect security without impacting on content-based routing, and the implications of federated multi-domain systems.We discuss the specification of policy using role-based access control, and demonstrate how to enforce the security of the communications API and the broker network.
