• VPN: VPN is the abbreviation for "virtual private network" and refers to a logically self-
contained network. A VPN connects a few known network nodes via encrypted
communication via a larger, potentially insecure network, e.g. Internet. If the web user
interface of the 7KN Powercenter 3000 can be accessed via the Internet, we strongly
recommend establishing a VPN connection between the web client (device on which the
web browser is running) and the router.
• Physical access protection: Unauthorized access or manipulation of networks and
electronic devices is possible without leaving visible traces. For that reason, physical
access protection for the installed 7KN Powercenter 3000 is necessary. The
7KN Powercenter 3000 should also be protected from unauthorized access when it is not
installed because the device could be manipulated without leaving visible traces. For
example, services could be activated at the external interface in order to be misused later.
