The water in a Tampa Bay plant was hacked remotely, raising the lye to dangerous levels

There are additional failsafes, yes. This would never have made it out into the pipes. The press is hyping this incident up quite a bit. Though if it encourages municipalities to get their network security shit together, then maybe it’s for the best,

No matter how automated the system is it ultimately falls to the operator to ensure proper operation of the equipment to achieve the desired outcome. Adding in extra layers of safety would help reduce risk but also introduces additional points of maintenance and failure (costs of operations increases and potential service outages). Ultimately if a hacker bricked the whole computer system the operators could flip some switches and run everything manually.

Prepare for more. This should get interesting. (I hate interesting.)
