EXHIBIT 15.14 CONNECTING MACHINE CAPABILITIES
324 Ch. 15 Service-Oriented Conceptual Architecture Modeling Principles
3. Security enhancement. A connecting machine can serve as an intermediary broker that
can enhance the security of a message passing through. This is typically achieved by
real-time security assertion mechanisms that provide authentication and authorization services.
For example, the well-known Security Assertion Markup Language (SAML)15 is
a commonly used technique that enables identity assertions into a Simple Object Access
Protocol (SOAP) message header in distributed and federated Web service environments.
A connection machine can also offer security mechanisms such as a digital certificate and
digital signatures to help protect a user??™s identity.
4. Binding and invocation. Connecting machines can provide message binding and invocation
of remote services.
5. Interoperability management. The connection machine can alleviate interoperability
challenges between dissimilar operating systems, platforms, and technological environments.
For example, it offers search capabilities via service registries and transparent
protocol bridging between federated technological environments. In other words, data and
protocols can be translated to enable seamless communications between heterogeneous
technologies.
