6.2 Network security/VPN device

NOTE: GE recommends that your Entellisys Low Voltage Switchgear system be equipped with a VPN/Firewall device if it is connected to a LAN that is also used for other purposes. Failure to do so could result in unauthorized access to the control and settings functions of the circuit breakers.

In addition to the standard username and password administrative functions for Entellisys, accessibility to control functions and parameter settings must be considered from the network point of view. The provisions for securing the network on which Entellisys communicates to HMI

6Control Stations and other SCADA systems depends greatly on how the network over which they communicate is configured.

•In-Gear HMI only – In this configuration, there is no network access external to the switchgear and therefore no implications for network security.

•In-Gear and Near-Gear HMIs – The implications for network security depend on the accessibility of the network the Near-Gear HMI uses to reach the main switchgear instrumentation compartment.

•In-Gear, Near-Gear, Remote HMIs, and SCADA system access – The implications for network security depend on the accessibility of the network the Near-Gear HMI uses to reach the main switchgear assembly.

GE provides a mechanical mounting assembly compatible with Juniper Networks NetScreen- 5GT VPN/Firewall Appliance. Since configuration of the device is mostly dependent on the specific network architecture of the facility in which it is installed, please consult the NetScreen documentation for assistance in configuring this device, or contact your local IT department or network service provider.

As a minimum, GE recommends that the VPN/Firewall appliance be configured to only permit communications between the devices in the switchgear instrument compartment and the external devices that are intended to communicate with them.
