Securing Web services for V5.x applications using identity assertion authentication
With the identity assertion authentication method, the security token generates a wsse:Username Token element that contains a wsse:Username element. On the request sender side, a callback handler is invoked to generate the security token. On the request receiver side, the security token is validated. Unlike basicauth authentication, trust is established through the use of a security token rather than through user name and password validation.
There is an important distinction between Version 5.x and V6.0.x and later applications. The information in this article supports V5.x applications only that are used with WAS V6.0.x and later. The information does not apply to V6.0.x and later applications. WebSphere Application Server provides several different methods to secure your Web services. Identity assertion authentication is one of these methods. You might also secure your Web services using any of the following methods:
- XML digital signature
- XML encryption
- Basicauth authentication
- Identity assertion authentication
- Signature authentication
- Pluggable token
Overview
To use identity assertion authentication to secure Web services, complete the following tasks:
Procedure
- Secure the client for identity assertion authentication.
- Configure the client for identity assertion: specifying the method
- Configure the client for identity assertion: collecting the authentication method
- Secure the server for identity assertion authentication.
- Configure the server to handle identity assertion authentication
- Configure the server to validate identity assertion authentication information
Results
After completing these steps, you have secured your Web services by using identity assertion authentication.
Configure the client for identity assertion: specifying the method
Configure the client for identity assertion: collecting the authentication method
Configure the server to handle identity assertion authentication
Configure the server to validate identity assertion authentication information
