By default, the Integration Server provides an HTTP port at 5555 that allows all hosts (identified by their IP addresses) to connect to it and allows access to all services through that port (unless prohibited by an ACL). Although this port is ideal for initial Integration Server installation and configuration, as well as many development environments, for deployment, you should replace this port with ports that allow connections from only specified IP addresses (those of your partners and users) and make only specified services available.

This section describes controlling access to resources at the port level. To control access using Access Control Lists, see Controlling Access to Resources with ACLs.
