Using Microsoft IIS
If you are planning to use Microsoft IIS as your WebSphere Commerce web server, you must install Microsoft IIS according to the Microsoft product documentation. After you have completed installing Microsoft IIS, you must install and configure WebSphere Commerce. The configuration of your web server is completed after you create a WebSphere Commerce instance.
Note: If you plan to use the IIS Web server
with WebSphere Commerce, you need to be aware of associated security
considerations and take the recommended actions to minimize any security
exposure of your WebSphere Commerce data. For more information, see Security consideration for the Internet Information Services (IIS) web server.
