Moxa | Securely Connect Older Modbus, DNP3, and Other Devices
Use protocol gateways without compromising security
When you use a protocol gateway to connect to older Modbus, Profibus, DNP3, or other devices, you need to be careful about exposing those devices to cybersecurity risks. That’s why we design our MGate 3000 and 5000 line of protocol gateways to be in full compliance with IEC 62443-2 security standards, and offer additional tools and resources to protect against unauthorized users.
Protect Against Unauthorized Access
User Authentication and Authorization
A common security vulnerability in industrial systems are devices that are still using the default manufacturer’s login and password. Our firmware requires administrators to change this password during configuration.
Security Hardening Guide
Our step-by-step security hardening guide helps you configure the MGate to minimize exposure to cybersecurity threats. You’ll see exactly which services are unnecessary and can be disabled for your use case.
Communication Integrity
Configuration access is protected through the support of secure protocols TLS 1.2, HTTPS, and SNMPv3. Insecure protocols (e.g., HTTP) are disabled by default.
Network Access Control
Additional functions such as IP address allowlist help you further limit network access so unauthorized users cannot make changes to device settings.
Tools to Monitor and Take Action
Security Advisories and Patches
You can subscribe to our Security Advisory page to make sure you are notified of any new vulnerabilities that have been discovered. We will provide mitigation guidance as well as links to download security patches and updated firmware as needed.
Visibility for Network Administrators
Our MXview network management suite provides easy visibility of your network topology and supported network devices. You’ll be able to see your MGate’s security status and set up user-defined notifications and alarms, so you can respond before an unauthorized user is able to wreak havoc.
Device Management
Our MXconfig utility and CLI configuration tools are powerful tools when you need to manage multiple MGate units and other supported network devices. In a few steps, you can back up or restore settings on each device, or update each device’s firmware to take advantage of any security patches.
