Security
Network Access
Access via Smart view:
One of the fundamental requirements of
»IT Security« is to prevent unauthorized persons from accessing the own
systems, including the protective device. The device offers access via its front panel, and via the operating software
Smart view.
Since the access via front panel is possible only for someone who is located directly in front of the device the risk
should normally be rather low, compared to the risk of unauthorized access via
Smart view, especially if the device
is part of an Ethernet / TCP/IP network.
After commissioning of the device, it is recommended to deactivate the
Smart
view access via Ethernet; this can be done with the setting parameter [Device
Para / HMI / Security]
»Smart view via Eth«.
Independent of this, there is also the option to deactivate the
Smart view
access via the USB interface; this can be done with the setting parameter
[Device Para / HMI / Security]
»Smart view via USB«.
For Line Differential devices there is the additional option to deactivate the
access to the remote device via Protection Communication; this can be done
with the setting parameter [Device Para / HMI / Security]
»Sm. view via
ProtCom«.
Note: If Smart view is used to deactivate the Smart view access, then the current session gets automatically
terminated.
SCADA Communication:
It is to be noted that there are always certain security risks related to the use of SCADA protocols. Detailed
information can be found in the technical literature.
Intranet Security:
If the Ethernet interface of the device is connected to a network, it is the responsibility of the user to maintain all
necessary means required for the security of the company network. In particular, it must be guaranteed that
external access (i. e. out of the internet) to the device has been made impossible. Please keep yourself informed
about up-to-date technology (firewalls, VPN etc.)!
