I'm not a pipeline expert, but I've been doing computers sense the early 90s. You have a pipe. It has pumps and valves. You have a computer that controls it all. The computer gets hacked. UNPLUG THE DAM COMPUTER... and plug in another one. Then restart the pumps. If they are too incompetent to figure out a workaround then get the hell out of the way and let someone else try.
If there is one thing I've learned with computers its that the guy at the console is god. There is no such thing as taking over from a remote location. Anyone that tells you differently has been watching too many movies. Send real actual human beings out the the pumps, unplug the dam computer and just turn the pump on manually. Yeah, a person might have to watch the pressure and flow rates etc rather than the computer. So the hell what. Get the dam gas flowing again morons.
Hey man ... I totally see where you are coming from. Here is the thing though, Stuxnet (if that is what it was) finds it's way into your SCADA and can fuck up the machinery all while reporting back to the control boards that everything is hunky-dory. If the hack managed to break some shit, it's not just the software that will need inspection and fixing, it will be the hardware that keeps thousands of gallons of wasp spray (liked your comment from earlier) from leaking out all over the local golf course, an into my favorite fishin' spot. I'm not too worried about being out of bourbon for a few weeks, but I'm not at all cool with high-octane catfish fillets. Nope ... not cool with that shit at all.
