This is so unnecessary ...
I work in telecom [as a consultant]. I always advise my clients that they should not put command and control functions of their equipment on to the Internet.
My clients can put alarm functions on the Internet that notify them when something is wrong. They then have to go to alternate modes of communication in order to control the equipment.
The alternate modes of communication? Either a dedicated T1 line or a dial-back modem [with username/password authentication].
Simple, secure, and relatively cheap - just the cost of doing business.
They not only shouldn’t put it on the internet. They shouldn’t have it on computers that are connected to the internet. It should be a closed system.

I commend dedicated point to point Ethernet to my customers for that purpose. Better bandwidth and the costs have dropped dramatically on those in the last few years.
