WebSphere® Application Server provides message-level protection for its security token service, known as the WebSphere Application Server trust service. For the trust service, you must use a special class of policy sets known as system policy sets.
Perform the following high-level steps. The order of the tasks is not important but all high-level required steps must be performed to complete the trust configuration.
After the configurations are completed and the trust service runtime configuration has been updated, you have used the administrative console to secure requests to the trust service by using system policy sets.
