Security aspects of the 7KN POWERCENTER 3000 as a gateway
The gateway function enables 7KN Powercenter 3000 and the connected devices to be
integrated into existing software applications.
The gateway function is transparent. Thus, the full scope of the addressed device is
available to the software application.
The operator must make sure that only authorized applications have access.
The following measures are recommended:

● IP filter (firewall whitelist)
