18.8.4.2 (L1) Ensure 'Remote host allows delegation of non-exportable credentials' is set to 'Enabled'

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

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.

Solution

To establish the recommended configuration via GP, set the following UI path to Enabled :

Computer Configuration\Policies\Administrative Templates\System\Credentials Delegation\Remote host allows delegation of non-exportable credentials

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template CredSsp.admx/adml that is included with the Microsoft Windows 10 Release 1703 Administrative Templates (or newer).

Impact:

The host will support the

Restricted Admin Mode

and

Windows Defender Remote Credential Guard

features.
