When using a single sign-on mechanism, security contexts are____________.
With SAML, the _____________ element is used by the relying party to confirm that a given message came from the subject specified in the assertion.
When establishing a single sign-on mechanism, the application of the Standardized Service Contract principle requires the use of SAML because it is an industry standard understood by multiple service consumers.
The application of the Service Composability principle can be supported by the application of the Brokered Authentication pattern.
A task service needs to access three entity services as part of a service composition. The task service needs to authenticate itself every time it accesses one of the three entity services. Because the task service must authenticate itself three times to complete its task, the current service composition design is considered inefficient. How can it be improved while continuing to fulfill the authentication requirements?
