VCL-2243: RTU Firewall IEC -104, IEC 61850 MMS,
MODBUS TCP/IP

Get Data Sheet

VCL-2243 is a high-security, high-reliability, ruggedized, failsafe transparent RTU Firewall that is designed to be installed between the RTU and the SCADA server without having to reconfigure any element of the network. VCL-2243 firewall supports IEC 60870-5-104 (IEC 104), IEC 61850 MMS protocol, MODBUS TCP/IP protocol options with extremely advanced features that may be installed to secure and protect RTUs (Remote Terminal Units) in critical infrastructure such as Sub-Stations, Smart Grid Distribution Systems, Oil and Gas Infrastructure and Railway Signalling Networks from being compromised, attacked, or accessed by hostile elements.

Protocol Supported:

IEC 60870-5-104:
10/100BaseT ETH Port IEC 61850 MMS:
10/100BaseT ETH Port MODBUS TCP/IP:
10/100BaseT ETH Port

Versions and Technology Deployment:

High-Security, High-Reliability, Ruggedized RTU Firewall.
Failsafe – Never itself becomes a point of failure, even in a power down condition.
Transparent Firewall – No modification required in the existing network.
Does not add any measurable latency. The latency added under full load conditions is less than 1ms.
Installed in sub-stations to protect RTUs from network side intrusion and hostile access.
MAC based lock. Allows user to lock to specified MAC addresses of known network devices in the utility network such as SCADA servers, and network management devices, computers etc. The RTU shall only accept or transmit data to known network devices in the MAC white-list.
IP Address based lock. Allows lock to user specified IP address. The RTU shall only accept or transmit data to known network devices in the IP address white-list.
Port based lock. Allows transmission only on user selected ports. Blocks communication and access on all other ports.
Deep Packet Inspection. Allows only SCADA (-104/MODBUS TCP/IP/ MMS) packets to pass through. Blocks all other packets.
Comprehensive logging of all -104/MODBUS TCP/IP/MMS packets. Finger-prints and logs all unauthorized traffic and access attempts.
Time keeping: Fetches time from NTP Server to maintain millisecond accuracy.

Applications:

Utilities: Electric generation, transmission and distribution.
May be installed to Firewall RTU Terminals and server(s) located in Load Dispatch Centres / SCADA Management Centres and Rail Traffic Control.
Smart Grid Distribution Systems.
Oil & Gas production, pipelines.
Railway Signalling Infrastructure: Rail Traffic Control Room(s).
All distributed data networks consisting of a central server and multiple edge locations.

SSH (Secure Access Control) with encrypted Password Protection

Interfaces - Terminal:

Total Number of Ethernet Interfaces: 2

One, 10/100 RJ45 equipment interface for the local (trusted) RTU side
One 10/100 RJ45 network interface to the WAN (untrusted) network side

Auto MDI/X (straight or crossover Ethernet cable correction)
Management interfaces:

Ethernet, RS-232, RS-485, USB

CE Compliances:

Immunity as per EN 60255-26
Low voltage directive as per EN 60255-27

Other Regulatory Compliances:

RoHS
Meets CE requirements
Complies with FCC Part 68 and EMC FCC Part 15

UNMS (Unified Network Management System)

Secure (supports TLS/SSL for encrypting connections between devices)
Permission-based security
Uses Software Defined Perimeter (SDP), the username/password login are replaced with Single-Packet Authorization (SPA) and the receiving device cannot be seen by hackers. This introduces an additional layer of security and is beneficial with or without SSL/TLS.
Guaranteed message delivery (no data loss or duplication of data)
