Safe from Cyber Attacks and Vulnerabilities
with Industrial Network Security
Modern industrial automation networks use TCP/IP protocols to simplify development and maintenance efforts and easily integrate with many different applications over an industrial Ethernet. The move to Ethernet has delivered tremendous benefits in efficiency and interoperability, but has also opened up industrial networks to communications from the outside world. Industrial network security requirements have evolved significantly in recent years and there is a growing recognition that industrial devices can be targets of sabotage. Any intrusion in the industrial control system can lower production quality and even cause significant damage and safety risks. A network system with effective Layer 2 security features, such as IEEE 802.1X, SSH, HTTPS, and port security, and security routers can greatly enhance the security and availability of the process control network infrastructure to achieve safe and efficient production while protecting critical SCADA and DCS systems from unexpected external and internal cyber attacks and vulnerabilities.

PLCs Easily Crashed by Cyber Attack
A survey from CERN (The European Organization for Nuclear Research) revealed that PLCs are often vulnerable to simple attacks when running free tools such as Netwox or Nessus.
83% of Cyber Storms Originate Internally
AT&T’s report mentions that most network security attacks are initiated by insiders with malicious intent.
The Best Practice:
Safeguard Infrastructure and Cyber Security by Applying Secure Firewall/VPN Solutions

Enable reliable and secure communication among remote corporate networks, SCADA,
and DCS networks at oil drilling facilities, pipelines, and refineries.
Create a secure framework to protect
critical field devices facing ever-evolving
cyber attacks.
Minimize security risk and threats
and achieve safe 24/7 operations.
A barrier to prevent unauthorized or unwanted access to an industrial control system.
A secure, private communication tunnel across WAN networks to provide remote offices with secure access to an industrial network.
Build Secure, High-speed Access for Oil & Gas Networks
EDR-G903 Series Industrial Firewall/VPN Secure Router
Moxa's EDR-G903 series, the leading Gigabit performance Firewall/VPN secure router, is designed to defend industrial networks. The EDR-G903 protects sensitive process control networks and mission-critical industrial assets by forming a trusted intranet environment. Moxa's EDR-G903 series supports 3 combo Gigabit ports with built-in RJ45 ports and SFP slots for connecting to a WAN, a LAN, and a WAN or DMZ (Demilitarized Zone) with rapid transfer bandwidth. The dual WAN feature is ideal for establishing a reliable Internet connection backup and for providing a secondary option for load sharing with two Internet service providers. A wide operating temperature range of -40 to 75ºC and smart firewall functions, such as Quick Automation Profile for enabling common Fieldbus protocols, make the EDR-G903 well-suited for harsh, industrial applications.
