Kerberos-based WS-Security

Kerberos is a network authentication protocol that enables mutual authentication with symmetric keys. Users and services on a network authenticate with each other through a Key Distribution Center (KDC), as a trusted third party. IBM® Integration Bus provides support for Kerberos either as a service or as a client.

You can use message flows to call web services that are secured with Kerberos by using a SOAP Request node. You can also provide web services that are secured with Kerberos by using SOAP Input Nodes. The WS-Security header passes Kerberos tokens. You can sign and encrypt either parts or all of a SOAP message by using Kerberos tokens. Signing and encrypting messages provides message integrity, confidentiality, and authenticity.
