EDR-G9010 secure routers UC-8200 IIoT gateway computers MOXA are working to expand their portfolio of IEC 62443-4-2 compliant products, with more devices expected to achieve compliance by 2025.
MOXA Industrial Linux
MOXA’s UC-8200 Arm-based computers, such as the UC-8210-T-LX or the UC-8220-T-LX models, feature MOXA Industrial Linux (MIL) which is developed according to IEC 62443- 4-1. MOXA Industrial Linux 3 Secure (MIL3) is IEC 62443-4-2 compliant.
The MIL3 operating system is based on Debian 11 with kernel 5.10 and offers advanced security features like TPM 2.0, hardware root of trust, secure boot, and disk encryption using LUKS . It also has quick backup and restore utilities and automated system recovery features based on an overlay file system architecture. If a security breach, process failure, or file corruption were to occur, these features
help to reduce downtime as much as possible.
MOXA provides long-term support for their Linux OS, with security updates and high-priority bug fi xes included in its 10-year lifecycle, as well as access to the MOXA Product Security Incident Response Team (PSIRT). The MOXA PSIRT investigates all reports of cybersecurity vulnerabilities that could affect MOXA products, proactively protecting them and effectively mitigating and managing security risks.
MIL being IEC 62443-4-2 certifi ed means that it has been rigorously evaluated and meets the high standards of cybersecurity required for industrial automation and control system components. The UC-8200 is described as the fi rst host device worldwide to attain IEC 62443-4-2 certifi cation, making it easier for asset owners and system integrators to integrate IIoT applications securely without extensively testing and validating the computing platform’s security . Speaking on the UC-8200 computers, George Y Hsiao, product manager of MOXA IPC Business, said: “The IEC 62443-4-2 certifi ed UC-8200 Series computer makes it easier for asset owners and system integrators to integrate IIoT applications by providing a
secure platform that has already been tested and validated. Without such a certifi ed platform, asset owners and system integrators would need to spend a signifi cant amount of time testing and validating the security of the computing platform and its components before integrating their applications.”
Security certainty with IEC 62443-4-2
IEC 62443-4-2 is not merely a suggestion – it’s a critical standard for enhancing the security capabilities of IACS components and is essential for manufacturers and operators aiming to implement robust cybersecurity measures. It ensures they meet legal and regulatory requirements like the NIS2 directive across energy, transportation and other critical sectors. The IEC 62443-4-2 certifi cation demonstrates MOXA’s proactive approach to safeguarding these critical infrastructures, making their solutions a reliable choice for industries seeking to strengthen their cybersecurity. By meeting these rigorous standards, MOXA devices ensure robust security features and provide engineers with the confi dence that their systems are
protected against evolving threats in the industrial automation sector.
At Impulse, we stock a range of MOXA devices that are IEC 62443-4-2 certifi ed, ensuring our customers have access to the highest cybersecurity standards in industrial automation. This means that the certifi ed devices we offer meet industry-leading security standards and are equipped to protect against cyber threats, providing robust performance in their critical operations to ensure the safety and reliability of your industrial control systems.
