Using web services policies, you can define the qualities
of service for your web services and clients.
The product provides several types of web services policy:
- WS-Addressing: Based on the Worldwide Web Consortium (W3C)
WS-Addressing specifications for web services. This family of specifications
provide transport-neutral mechanisms to address web services and to
facilitate end-to-end addressing. This specification provides asynchronous
support.
- WS-Security: Based on the WS-Secure Conversation (WS-SC)
and WS-Security specifications, as well as the associated token profiles.
The WS-Security specification and its associated token profiles define
a way to send security tokens and provide message integrity and confidentiality.
The WS-Secure Conversation specification establishes a secure context,
on the basis of shared keys, for the client and server to use for
a series of messages. This standard provides a framework across organizations
that defines how to secure the entire conversation. Use the WS-Security
policy to define how the SOAP messages are secured. You can also use
WS-Security policies to define the bootstrap policy that is used to
acquire security context tokens. Security context tokens are used
by secure conversation.
- WS-Reliable Messaging (WS-RM): Enables the sender and receiver
to assure the quality of services in a set of messages. With this
policy, you can address latency issues, maintenance interruption,
and other problems that prevent messages from being completed. This
quality assurance is critical for stateful applications.
- WS-Transaction: Provides support for atomic transactions
in a web services environment. This quality of service enables web
service applications and the resources that they use to participate
in distributed global transactions.
- HTTP Transport: Applies HTTP features and HTTP connections
polices to outbound messages. The response listener policy is enforced
on inbound messages.
- SSL Transport: Provides SSL transport security for the
HTTP protocol with web services applications.
