You can configure your Integration Server to present different server certificates with different ports. One reason to do this is so that different ports can provide different SSL security levels. You determine the security level of a certificate during the certificate signing process. You tell the certificate authority which class of certificate you need and it creates a certificate with those attributes. Later, when you configure your ports, you specify the certificate that has the security level you want to associate with that port. See Setting Up Aliases for Remote Integration Servers for instructions on configuring your ports.
