Secure web services for Version 5.x applications using identity assertion authentication
With the identity assertion authentication method, the security token generates a <wsse:UsernameToken> element containing 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.
Important: There is an important distinction between Version 5.x and Version 6.0.x and later applications. The information supports Version 5.x applications only used with WAS v6.0.x and later. The information does not apply to Version 6.0.x and later applications.
WebSphere Application Server provides several different methods to secure the web services. Identity assertion authentication is one of these methods. We might also secure the web services using any of the following methods:
- XML digital signature
- XML encryption
- BasicAuth authentication
- Identity assertion authentication
- Signature authentication
- Pluggable token
To use identity assertion authentication to secure web services, complete the following tasks:
- 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.
Results
After completing these steps, we have secured the web services by using identity assertion authentication.
