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:
• Use of VPN (VPN = Virtual Private Network), see also chapter Further recommended
security measures (Page 40).
• IP filter in external routers, switches and firewalls
• IP filter (Firewall Whitelist) in 7KN Powercenter 3000
