This was someone who was involved in installing the control system. That is a lot different from someone doing this cold. I mentioned somewhere that most security breaches had an inside man involved, as was this. Even the most secure systems can be defeated by someone working on the inside to create holes in the system.
Like a mail-sorting system used by the USPS. Went around teaching all the regional offices how to startup/use the machine, it included a PC interface.
First thing one guy did was 'prove' how unreliable it was by hitting F2 during the boot up, go into the PC bios and screw it all up. He wanted to make the point that 'the new system let me screw it up!'

I know what I've used. Where I used to work we did many water and wastewater projects with radio telemetry. If we had favorable conditions, we used Microwave Data Systems radio modems for the unlicensed
928MHz spread-spectrum band. When more power was required, we used EF Johnson VHF or UHF radio modems, for which the owner had to have the frequencies licensed.This is in the U.S. Your local rules, available products and mileage will vary.

..which probably explains why virtually every BIOS now includes password protection. A no-cost adder that allows COTS equipment in "hostile user" (as opposed to "user hostile") environments.

SCADA systems allow one to monitor and control equipment from a remote location. That's the advantage. The disadvantage is that they cost money to install and maintain, add additional system failure modes and can be a security loophole.
One of the advantage is that the operators of the plants do not have to keep hundreds of track records of log sheets anymore as any data recorded on the Scada system can be accesed at the convinience.
