You can restrict access to your JSM instance by using TCP/IP client address filtering.
...
It is impossible for another machine or network scanner to access the TCP/IP interface.

Multihomed LOOPBACK address
You can use multiple LOOPBACK addresses for multiple JSM instances and use the same port number.

The following text is from the DDTCPIFC *LOOPBACK help section:
...
The interface being changed is theloopback or LOCALHOST interface.

Because processing associated with loopback does not extend to a physical line, there is no line description associated with a loopback address.

This special value must be used for any INTNETADR that has a first octet value of 127.
