Securing web services, to be invoked over the Internet, is both essential and difficult. Using appropriate tools and technologies makes it easier to accomplish the task. Developer-dependent solution, where security is embedded directly into consumers and providers, is inflexible and labour-intensive. Gateway-based solutions are more flexible, more dynamic and easier to manage. In this note Java CAPS 6-based web service consumer and provider pair are developed. The solutions are exercised first without, then with the web services security gateway. This enables demonstration of how web services can be secured, how policies can be developed and propagated and how WS-Security-mandated XML markup can be dealt with outside the development shop. The Layer 7 SecureSpan XML Gateway, and its oft forgotten companion, the SecureSpan VPN Client, are used to explore the topic. The reader should be able to acquire enough knowledge to obtain and deploy the SecureSpan XML Gateway, and to use its basic functionality to implement gateway-mediated secure web services solutions.
