Srijith K. Nair, Ivan Djordjevic, Bruno Crispo, Theo Dimitrakos · 2007
Web Services and SOA provide interoperability and architectural baseline for flexible and dynamic cross enterprise collaborations, where execution and use of the participating services contributes to the common objective. Relationships within these collaborations are complex, with services joining and leaving throughout the life cycle, or the same services being offered in several collaborations simultaneously. This provides strong requirements for federated security, where integrity and confidentiality of the collaboration must be maintained through membership control, security policy enforcement and separation of web service instance interactions in different collaborations.
