Firewall policy settings for endpoint security in Intune

  • מאמר

View the settings you can configure in profiles for Firewall policy in the endpoint security node of Intune as part of an Endpoint security policy.

Applies to:

  • macOS
  • Windows 10
  • Windows 11

Note

Beginning on April 5, 2022, the Firewall profiles for the Windows 10 and later platform were replaced by the Windows platform and new instances of those same profiles. Profiles created after that date use a new settings format as found in the Settings Catalog. With this change you can no longer create new versions of the old profile and they are no longer being developed. Although you can no longer create new instances of the older profile, you can continue to edit and use instances of it that you previously created.

For profiles that use the new settings format, Intune no longer maintains a list of each setting by name. Instead, the name of each setting, its configuration options, and its explanatory text you see in the Microsoft Intune admin center are taken directly from the settings authoritative content. That content can provide more information about the use of the setting in its proper context. When viewing a settings information text, you can use its Learn more link to open that content.

The settings details for Windows profiles in this article apply to those deprecated profiles.

Supported platforms and profiles:

  • macOS:

    • Profile: macOS firewall

  • Windows 10 and later:

    • Profile: Windows Firewall
