How do I start with WS-Security in EAP 6?

Issue

• How do I start with WS-Security in EAP 6 ?
• How do I configure a web service to use ws-security ?
• We are trying to set up one way authentication to allow/block the execution of web services already written. Your documentation states there is a way to do this through switchyard, cxf interceptors, annotations and or spring via xml files.
