[Nut-upsuser] why upsc need no authentication?

[d tbsky]

Hi:
     I  found I can setup password for uspmon. but upsc can connect to
any upsd without authentication. although the ups data is not very
confidential, but I would like not to expose it to anyone who can
connect to server.

    is there any method to harden upsd? thanks for hint.

Regards,
