I’m a controls engineer that wrote the controls for the Owens Lake reclamation project.
Owens Lake once had a fishing industry, casino boats and vacation homes.
LA installed pipes and drank it all to a hard desert wasteland that contributed more silicate particulate pollution then any other source detected in Antarctica even.
We tapped into the California aqueduct with an 8 foot in diameter pipe. The on off valve takes three days to open or close because there’s as much kinetic energy in that pipe as there is in railroad locomotive pulling 400 train cars.
Something we don’t want anyone to gain control of, so the control network is on an entirely isolated network, hence unhackable remotely.
Even if you “NEED” your control system to have remote access you can connect via the dark web with VPN and 2048 bit encryption or stronger when it becomes available.
All the banks use the dark web you don’t hear them complaining publicly about cyber security.
20% of the dark web is criminal, they sell heroin on a web page for goodness sake, US intelligence can’t find them so they advertise there.
That’s how secure it is.
Try the TOR browser it’s kind of jarring.
