Securing 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 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.
Before you begin
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 that
are used with WebSphere® Application Server Version 6.0.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 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
