Introduction

The EDR-G903 series is a high-performance, industrial VPN server with a firewall/NAT all-in-one secure router. It is designed for Ethernet-based security applications in sensitive remote control or monitoring networks, and it provides an Electronic Security Perimeter for the protection of critical cyber assets such as pumping stations, DCS, PLC systems on oil rigs, and water treatment systems. The EDR-G903 series includes the following cybersecurity features:

• Virtual Private Network (VPN): VPNs are designed to provide users with secure communication links when accessing a private network from the public Internet. They use IPSec (IP Security) server or client mode for encryption and authentication of all IP packets at the network layer to ensure confidentiality and sender authentication.
• Firewall: Controls network traffic between different trust zones. Network Address Translation (NAT), which shields the internal LAN from unauthorized activity from outside hosts, is included.

The EDR-G903’s Quick Automation Profile function supports most common fieldbus protocols, including EtherCAT, EtherNet/IP, FOUNDATION Fieldbus, Modbus/TCP, and PROFINET. Users can easily create a secure Ethernet Fieldbus network from a user-friendly web UI with a single click. In addition, Moxa’s PacketGuard technology (Deep Packet Inspection) helps to filter Modbus TCP commands at OSI layer 7. The wide temperature range models that are available operate reliably in hazardous, -40 to 75°C environments.

Whitepaper: The right industrial firewall can strengthen the safety and reliability of control systems

In this paper, we present important considerations for implementing network security and network security risk management. We also include information on how to develop mitigation strategies for specific problems and provide directions on how to choose the right industrial firewall to ensure safety and reliability for industrial networks

White Paper: Protecting Industrial Control Systems with Gigabit Cybersecurity

An Industrial Control System (ICS) needs the type of network security that takes into consideration its central role in industrial applications. Problems that arise in ICS operations can result in losses on many different levels, including costs incurred from equipment damage, and even loss of life. Although ICS networks may use some of the same technology and devices as enterprise IT systems, from a hands-on practical point of view, ICS network security differs in three aspects: protecting devices, content for filtering, and operating environment
