About the article

This article aims to challenge the reader to think about security-as-a-service within an SOA. In this paper, we focus on an example of security as an infrastructure service in the context of an Enterprise Service Bus (ESB). We discuss the SOA architectural model and how the SOA principles can influence the definition of security as part of an overall service model, the benefits of a SOA based approach to security infrastructure components in a business environment and some typical patterns of the deployment of a SOA-security infrastructure.
