Information

Remote host allows delegation of non-exportable credentials. When using credential delegation, devices provide an exportable version of credentials to the remote host. This exposes users to the risk of credential theft from attackers on the remote host. The Restricted Admin Mode and Windows Defender Remote Credential Guard features are two options to help protect against this risk.

The recommended state for this setting is: Enabled.

Note: More detailed information on Windows Defender Remote Credential Guard and how it compares to Restricted Admin Mode can be found at this link: Protect Remote Desktop credentials with Windows Defender Remote Credential Guard (Windows 10) | Microsoft Docs

Rationale:

Restricted Admin Mode was designed to help protect administrator accounts by ensuring that reusable credentials are not stored in memory on remote devices that could potentially be compromised. Windows Defender Remote Credential Guard helps you protect your credentials over a Remote Desktop connection by redirecting Kerberos requests back to the device that is requesting the connection. Both features should be enabled and supported, as they reduce the chance of credential theft.

Impact:

The host will support the Restricted Admin Mode and Windows Defender Remote Credential Guard features.

Solution

To establish the recommended configuration, set the following Device Configuration Policy to Enabled:
To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Administrative Templates)

Click Create

Enter a Name

Click Next

Configure the following Setting

Path: Computer Configuration/System/Credentials Delegation
Setting Name: Remote host allows delegation of non-exportable credentials
Configuration: Enabled

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.or newer).

Default Value:

Disabled. (Restricted Admin Mode and Windows Defender Remote Credential Guard are not supported. Users will always need to pass their credentials to the host.)
