List of the settings in the Windows 365 Cloud PC security baseline in Intune

  • Статия

This article is a reference for the settings that are available in the Windows 365 Cloud PC security baseline that you can deploy with Microsoft Intune.

For each setting we list the baselines default configuration, which is also the recommended configuration for that setting provided by the relevant security team. Because products and the security landscape evolve, the recommended defaults in one baseline version might not match the defaults you find in later versions of the same baseline. Different baseline types, like the MDM security and the Defender for Endpoint baselines, could also set different defaults.

When the Intune UI includes a Learn more link for a setting, we include that here as well. Use that link to view the settings policy configuration service provider (CSP) or relevant content that explains the settings operation.

When a new version of a baseline becomes available, it replaces the previous version. Profiles instances that you’ve created prior to the availability of a new version:

  • Become read-only. You can continue to use those profiles but can't edit them to change their configuration.
  • Can be updated to the latest version. After you update a profile to the current baseline version, you can edit the profile to modify settings.

To learn more about using security baselines, see:

Windows 365 Cloud PC security baseline version 24H1:

The settings in this baseline apply to Windows devices managed through Intune. When available, the setting name links to the source Configuration Service Provider (CSP), and then displays that settings default configuration in the baseline.
