Moxa Launches World's First Industrial Computer With IEC 62443-4-2 Host Device Certification

Jan. 31, 2023 - With the release of its newest Industrial Linux 3 (MIL3) platform, Moxa has delivered the world’s first host device to attain ISA/IEC 62442-4-2 certification—the UC-8200 Series computer. IEC 62443-4-2 certification ensures that Moxa UC-8200 computers incorporate an advanced suite of secure-by-design hardware and software features to protect data and infrastructure against the rising threat of cyberattacks. 
“The IEC 62443-4-2 certified UC-8200 Series computer makes it faster, easier and more cost-effective to integrate IIoT applications by providing a secure platform that has already been tested and validated,” said George Hsiao, product manager of Industrial Embedded Computer at Moxa. “Without this certified platform, asset owners and system integrators would need to spend a significant amount of time testing and validating the security of the computing platform and its components before integrating their applications.” 
Built around a Cortex-A7 dual-core processor and offering flexible interfacing options, Moxa UC-8200 Series embedded computers serve as reliable and secure gateways for data acquisition and processing at field sites as well as versatile communications platforms for many other large-scale deployments.

Increasing operational resilience   

As Operational Technology and Informational Technology (OT/IT) continue to converge, the need for enhanced network security, endpoint protection, strong reliability, and a long lifecycle becomes critical for the development of next-generation industrial IoT systems that can effectively defend against cyber threats.
The UC-8200 Series computer comes with a security-hardening guide to help maintain it throughout its entire lifecycle—from integration and installation to operation, maintenance and decommissioning. It also includes a security diagnostics utility that allows customers to confirm that the UC-8200 Series computer remains compliant with IEC 62443-4-2 during the integration stage. Powered by an Armv7 Cortex-A7 dual-core 1 GHz processor, it also has Dual SIM slots and a microSD socket, two auto-sensing 10/100/1000 Mbps Ethernet ports, one CAN port, and a DIN-rail mountable IP30 metal housing with a wide temperature range of -40° to 85° C. 
Additional security features include:

  • Hardware root of trust 

The UC-8200 Series computer incorporates a one-time programmable (OTP) fuse and Trusted Platform Module (TPM) 2.0 technology to establish a hardware-based chain of trust that safeguards the Secure Boot process and software updates. This blocks hackers from taking control of the device during boot time and prevents malicious updates from being used for malware exploitation. 

  • Reliable and fast recovery 
Device availability is critical in industrial automation and control systems (IACS). That is why Moxa Industrial Linux 3 (MIL3) comes equipped with quick backup and restore utilities, as well as automated system recovery features based on an overlay file system architecture. This helps to reduce downtime in the event of a security breach, process failure or file corruption, such as a power outage during a critical update.
  • Robust connectivity and network management 

MCM (Moxa Connect Manager) easily optimizes LAN and WAN network availability by automatically switching between Ethernet, Wi-Fi, and LTE connections, which can minimize downtime caused by network unavailability or DOS attacks.

  • Superior Long-term Support 

Moxa provides long-term after-sales support and Debian-based distributions with 10-year life cycles to support UC-8200-equipped systems, including security patches, bug fixes, and access to the Moxa Product Security Incident Response Team (PSIRT) that takes a proactive approach to protect Moxa products from cybersecurity vulnerabilities and effectively mitigate and manage security risks.
Pascal LeRay, head of Cybersecurity at Bureau Veritas (BV), the global certification body that issued the ISASecure CSA Security Level 2 certification for the UC-8200 Series industrial computers, commented: “It is a great honor to assist Moxa in successfully obtaining IEC 62443-4-2 certification and to empower the company in better grasping the overall security issues and quality of product development through IEC 62443 to enhance its competitiveness. IEC 62443 universal standards for industrial control and information security have become mandatory technical requirements in many countries. Furthermore, as demand for product security increases, the importance of IEC 62443-4-2 has increased significantly, resulting in a growing number of customers requiring proof of security level from manufacturers for their Industrial IoT equipment."
UC-8200 series highlights:

  • Developed according to IEC 62443-4-1 standard and compliant with IEC 62443-4-2 industrial cybersecurity Security Level 2 standard 
  • IEC 62443-4-2 compliant diagnostic tool and security-hardening guide 
  • Automatic failover between Wi-Fi, cellular, and Ethernet connections for reliability and high availability 
  • Automatic system failover for system recovery and file backup 
  • TPM 2.0 for hardware root of trust authentication to prevent malware takeover or tampering 
  • A host-based Intrusion detection system (HIDS) and network security monitoring 
  • Optional built-in cellular and additional Mini PCI Express (mPCIe) slot for Wi-Fi modules 
  • Moxa Industrial Linux 3 with 10-year long-term support
