Web service providers establish transport-layer security using HTTPS. HTTPS uses SSL to provide the following security functions:

When you import web service definitions and Web Services Consumer transformations from a WSDL file located on a web server and the URL for the web server begins with HTTPS, the web service provider uses SSL. Similarly, when an endpoint URL configured in a Web Service application connection or contained in a WSDL file begins with HTTPS, the web service provider uses SSL. During a session with web service definitions or Web Services Consumer transformations imported from a web service provider using SSL, the PowerCenter Integration Service reads and writes data using transport-layer security.
