Request receiver
The request receiver defines the security requirement of the SOAP message. The security handler on the request receiver side of the SOAP message enforces the security specifications defined in the IBM extension deployment descriptor (ibm-webservices-ext.xmi) and bindings (ibm-webservices-bnd.xmi).
There is an important distinction between V5.x and Version 6 and later applications. The information in this article supports Version 5.x applications only that are used with WAS V6.0.x and later. The information does not apply to V 6 and later applications.
The security constraint for request sender must match the security requirement of the request receiver for the server to accept the request. If the incoming SOAP message does not meet all the security requirements defined, then the request is rejected with the appropriate fault code returned to the sender. For security tokens, the token is validated using JAAS login configuration and authenticated identity is set as the identity for the downstream invocation.
For example, if there is a security requirement to have the SOAP body digitally signed by Joe Smith and if the SOAP body of the incoming SOAP message is not signed by Joe Smith, then the request is rejected.
We can define the following security requirements for the request receiver:
- Required integrity (digital signature)
- We can select multiple parts of a message to sign digitally.
The following list contains the integrity options:
- Body
- Time stamp
- Security token
- Required confidentiality (encryption)
- We can select multiple parts of a message to encrypt.
The following list contains the confidentiality options:
- Body content
- Token
We can have multiple security tokens.
The following list contains the security token options:
- Basic authentication, which requires both a user name and a password
- Identity assertion, which requires a user name only
- X.509 binary security token
- LTPA binary security token
- Custom token, which is pluggable and supports custom-defined tokens validated by the JAAS login configuration
- Received time stamp
- We can have a time stamp for checking the timeliness of the message.
- Time stamp
