Set preferences for Microsoft Defender for Endpoint on macOS

Applies to:

This article contains instructions for how to set preferences for Microsoft Defender for Endpoint on macOS in enterprise organizations. To configure Microsoft Defender for Endpoint on macOS using the command-line interface, see Resources.

Summary

In enterprise organizations, Microsoft Defender for Endpoint on macOS can be managed through a configuration profile that is deployed by using one of several management tools. Preferences that are managed by your security operations team take precedence over preferences that are set locally on the device. Changing the preferences that are set through the configuration profile requires escalated privileges and is not available for users without administrative permissions.

This article describes the structure of the configuration profile, includes a recommended profile that you can use to get started, and provides instructions on how to deploy the profile.

Configuration profile structure

The configuration profile is a .plist file that consists of entries identified by a key (which denotes the name of the preference), followed by a value, which depends on the nature of the preference. Values can either be simple (such as a numerical value) or complex, such as a nested list of preferences.

The layout of the configuration profile depends on the management console that you are using. The following sections contain examples of configuration profiles for JAMF and Intune.

The top level of the configuration profile includes product-wide preferences and entries for subareas of Microsoft Defender for Endpoint, which are explained in more detail in the next sections.

Antivirus engine preferences

The antivirusEngine section of the configuration profile is used to manage the preferences of the antivirus component of Microsoft Defender for Endpoint.

To get started, we recommend the following configuration for your enterprise to take advantage of all protection features that Microsoft Defender for Endpoint provides.

The following configuration profile (or, in case of JAMF, a property list that could be uploaded into the custom settings configuration profile) will:

  • Enable real-time protection (RTP)
  • Specify how the following threat types are handled:
    • Potentially unwanted applications (PUA) are blocked
    • Archive bombs (file with a high compression rate) are audited to Microsoft Defender for Endpoint logs
  • Enable automatic security intelligence updates
  • Enable cloud-delivered protection
  • Enable automatic sample submission

Full configuration profile example

The following templates contain entries for all settings described in this document and can be used for more advanced scenarios where you want more control over Microsoft Defender for Endpoint on macOS.

Property list for JAMF full configuration profile

Intune full profile

Property list validation

The property list must be a valid .plist file. This can be checked by executing:

If the file is well-formed, the above command outputs OK and returns an exit code of 0 . Otherwise, an error that describes the issue is displayed and the command returns an exit code of 1 .

Configuration profile deployment

Once you’ve built the configuration profile for your enterprise, you can deploy it through the management console that your enterprise is using. The following sections provide instructions on how to deploy this profile using JAMF and Intune.

JAMF deployment

From the JAMF console, open Computers > Configuration Profiles, navigate to the configuration profile you’d like to use, then select Custom Settings. Create an entry with com.microsoft.wdav as the preference domain and upload the .plist produced earlier.

You must enter the correct preference domain ( com.microsoft.wdav ); otherwise, the preferences will not be recognized by Microsoft Defender for Endpoint.

Intune deployment

Open Manage > Device configuration. Select Manage > Profiles > Create Profile.

Choose a name for the profile. Change Platform=macOS to Profile type=Custom. Select Configure.

Save the .plist produced earlier as com.microsoft.wdav.xml .

Enter com.microsoft.wdav as the custom configuration profile name.

Open the configuration profile and upload the com.microsoft.wdav.xml file. (This file was created in step 3.)

Select OK.

Select Manage > Assignments. In the Include tab, select Assign to All Users & All devices.

You must enter the correct custom configuration profile name; otherwise, these preferences will not be recognized by Microsoft Defender for Endpoint.
