Originally, the SOAP specification left security issues open; thus, several proposals evolved to bridge the security gaps. The SOAP security extension, included with WebSphere Application Server - Express, is a security architecture based on the SOAP security specification, and widely accepted security technologies such as Secure Sockets Layer (SSL).
See these subtopics for more information about securing Web services that you publish using the SOAP protocol:
