Rule Text

Windows Server 2022 must be configured to enable Remote host allows delegation of nonexportable credentials.

Description

Discussion Text

An exportable version of credentials is provided to remote hosts when using credential delegation which exposes them to theft on the remote host. Restricted Admin mode or Remote Credential Guard allow delegation of nonexportable credentials providing additional protection of the credentials. Enabling this configures the host to support Restricted Admin mode or Remote Credential Guard.
