Traditional cloud integration scenarios, as adopted by many organizations, assume business processes to be executed in a cross-domain context, connecting on-premise and cloud applications. The emerging model of cloud-based integration platforms extends these scenarios by transferring business process execution entirely to the cloud. Although this approach provides numerous benefits and opens a new range of opportunities, its adoption requires reconsideration of currently applied practices and their adjustment to a new perspective.

In this work, we analyze the existing approaches to cross-domain service composition based on cloud integration platforms. We particularly focus on the security of these approaches, considering currently dominant OAuth 2.0 web authorization protocol and emerging UMA protocol. For this purpose, we present a new tool that enables UMA support in Apache Camel integration framework. We then analyze and discuss the integration flows relying on both protocols. Finally, based on RMIAS framework, we provide a security assessment of both approaches, presenting an overview of issues and challenges for future work.
