OT monitoring software versions

The Microsoft Defender for IoT architecture uses on-premises sensors and management servers.

This article lists the supported software versions for the OT sensor and on-premises management software, including release dates, support dates, and highlights for the updated features.

For more information, including detailed descriptions and updates for cloud-only features, see What's new in Microsoft Defender for IoT? Cloud-only features aren't dependent on specific sensor versions.

Versioning and support for on-premises software versions

This section describes the servicing information, timelines, and guidance for the available on-premises software versions.

Version update recommendations

When updating your on-premises software, we recommend:

  • Plan to update your sensor versions to the latest version once every 6 months.

  • Update to a patch version only for specific bug fixes or security patches. When working with the Microsoft support team on a specific issue, verify which patch version is recommended to resolve your issue.

Note

If you have an on-premises management console, make sure to also update your on-premises management console to the same version as your sensors.

For more information, see Update Defender for IoT OT monitoring software.

On-premises monitoring software versions

Cloud features may be dependent on a specific sensor version. Such features are listed below for the relevant software versions, and are only available for data coming from sensors that have the required version installed, or higher.

Threat intelligence updates

Threat intelligence updates are continuously available and are independent of specific sensor versions. You don't need to update your sensor version in order to get the latest threat intelligence updates.

For more information, see Threat intelligence research and packages.

Support model

Defender for IoT provides 1 year of support for every new version, starting with versions 22.1.7 and 22.2.7. For example, version 22.2.7 was released in October 2022 and is supported through September 2023.

Earlier versions use a legacy support model, with support dates detailed for each version.

On-premises appliance security

The OT network sensor and the on-premises management console are designed as a locked-down security appliance with a hardened attack surface. Appliance access and control is allowed only through the management port, via HTTP for web access and SSH for the support shell.

Defender for IoT adheres to the Microsoft Security Development Lifecycle throughout the entire development lifecycle, including activities like training, compliance, code reviews, threat modeling, design requirements, component governance, and pen testing. All appliances are locked down according to industry best practices and should not be modified.

Maintain your sensors and on-premises management consoles, for activities like backups, log exports, or health monitoring, via the web interface, or the Defender for IoT CLI commands.

Important

Manual changes to software packages or additions of external packages may have detrimental security or functional effects on the sensor and on-premises management console. Microsoft is unable to support deployments with manual changes made to software packages.
