Vulnerability Discussion

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 non-exportable credentials providing additional protection of the credentials. Enabling this configures the host to support Restricted Admin mode or Remote Credential Guard.
