Moxa Industrial Linux

Secure Edge, Trusted Platform

Our Commitment

Secure and Reliable Solutions for Decades to Come


Moxa, a dedicated member of the Civil Infrastructure Platform (CIP) and OpenChain Project under The Linux Foundation® and also a Linux Debian sponsor of the Debian Long Term Support (LTS) initiative, is committed to ensuring long-term stability for Debian-based systems. In line with this commitment, Moxa delivers Moxa Industrial Linux (MIL)—a secure, industrial-grade Debian-based Linux operating system.


MIL offers industry-leading 10-year OS support with security patches, which combined with the world’s first IEC 62443-4-2 Security Level 2 certified computer provides unmatched long-term reliability. Built on Debian and the standard Linux kernel, MIL accelerates application development and time-to-market with intuitive Moxa utilities for system, network, and I/O management.

The Foundation of Industrial Stability

Moxa Industrial Linux (MIL) is a reliable and secure open-source Debian-based operating system that leverages the Civil Infrastructure Platform (CIP) to provide long-term stability to your applications. Our focus is on quick deployment and long-term support of the Linux kernel for system stability and security, eliminating frequent major upgrades. In addition, built-in user-friendly utilities streamline system tasks such as data management, wireless connectivity, I/O interface control, and asset security.


Moxa System Manager (MSM)

MSM enables full-system snapshots and backup and restore for quick recovery after system failures. MSM supports system failover during system bootup, factory reset, and decommissioning to help maintain system availability and life-cycle management.

Moxa Connection Manager (MCM)

MCM offers an intuitive GUI for configuring and prioritizing Ethernet, Wi-Fi, and cellular network profiles. MCM maintains connections with failover and failback, even during the cyberattacks. MCM supports connection diagnostics, making it ideal for applications requiring reliable network switching and multi-channel connectivity.

Moxa Computer Interface Manager (MCIM)

MCIM simplifies system integration by providing a unified interface for managing various I/O hardware and non-standard components—such as DI/DO, buttons, disks, buzzers, and RS-232/422/485 mode switching. With CLI support, MCIM eliminates the need to adapt control logic for different SoC platforms, reducing complexity and accelerating application development.

Moxa Software Updater (MSU)

MSU enables you to keep the Moxa Industrial Linux up-to-date with the latest security patches, including fixes for known common vulnerabilities and exposures (CVEs). MSU supports both online and offline updates and includes an auto-recovery mechanism to ensure a safe update process even if an update fails.

Moxa Guardian

Moxa Guardian enables security diagnostics to evaluate the compliance of the device with IEC 62443-4-2 Security Level 2 requirements. It compares current system settings against the recommended secure baseline, identifies deviations, and provides actionable suggestions—including an option for a one-click remedy—to help users maintain both compliance and security robustness.

Secure Boot

Secure Boot performs a Chain-of-trust validation starting with the SoC’s OTP fuse validation of the bootloader, which then verifies the Linux kernel. The kernel checks system footprints using TPM. Only if the system footprints match Moxa’s factory-set policy, TPM provides the LUKS key to decrypt the root filesystem.
