I would have thought some of these should be airgapped for security reasons by design? Is it so hard to go to work these days that you have to hook it up to the outside?
These systems aren't just ignorantly plugged-in to an internet connection. But still, you NEED to be able to input data to them, including software updates, and you NEED to get data out, like real-time status updates sent to grid operators. Having someone typing-in every bit of data won't work, and connecting it to internet-connected systems by any method, such as RS-232 serial or others, or just sneakerneting with USB, DVD-Rs, etc., offers the possibility of hacking.
