WebSphere® Application
Server provides several
different methods to secure your web services. XML digital signature
is one of these methods.
Before you begin
Important: There is an important
distinction between
Version 5.x and Version 6 and later applications. The information
in this article supports Version 5.x applications only that
are used with WebSphere Application Server Version 6.0.x and
later. The information does not apply to Version 6 and later applications.
You
can secure your web services by using any of the following methods:
- XML digital signature
- XML encryption
- BasicAuth authentication
- Identity assertion
authentication
- Signature authentication
- Pluggable
token
About this task
With the signature authentication
method, the request sender
generates a signature security token using a callback handler.
The security token returned by the callback handler
is inserted in the SOAP message. The request receiver retrieves the
Signature security token from the SOAP message and validates it using
a Java Authentication and Authorization Service
(JAAS) login module. To use signature authentication to secure Web
services, complete the following tasks:
Procedure
- Secure
the client for signature authentication.
- Configuring the client for signature authentication: specifying the method.
- Configuring the client for signature authentication: collecting the authentication information.
- Secure the server for signature
authentication.
- Configuring the server to support signature authentication.
- Configuring the server to validate signature authentication information.
Results
After completing these
steps, you have secured your web services
using signature authentication.
