So here we go again... Some uncontrollable thing is going to disrupt our electric grid and technological infrastructure!
Just over a decade ago it was Y2K. Folks where stockpiling food, water and fuel for generators in fear that the electric grid was obviously going down at 12:00AM January 1, 2000 when all their 2 digit year clocks rolled over.
Since then, I've heard stories about people who fear an EMP that will take out the grid and are out stocking up on food, water, fuel getting ready to live without power for years..
Last week, here on slashdot, we had a story on a huge solar storm powerful enough to bring down the grid... Folks where encouraged to stock up, by food, water, fuel and prepare for weeks without power..
So, here we are today discussing a cyber attack on the power grid that could bring the grid down.... Need I type the rest?
Really? Look, it would *really* suck if the power grid in North America went down. Yes people would die and it would be a huge mess to fix with disruptions in food supplies and fuel. Of all the ways the grid could be disabled, cyber attack is the least likely and the one easiest to fix. It's unlikely to take the whole grid down unless the saboteurs where extremely crafty and organized. They would have to first find enough infrastructure to access, manage to break in, understand how all the stuff they could control was interconnected and what failures they could induce and THEN coordinate all the individual attacks well enough to actually do something more than just local damage before they cut power to enough infrastructure they needed to continue the attack. How all the infrastructure is connected and interrelates are not easy problems to solve.
We have bigger fish to fry than fearing some mythical cyber attack on infrastructure like the power grid. I won't say it will NEVER happen, but you are talking about something that his bordering on impossible. This is like Y2K. A bunch of Chicken Little's that don't have a clue about how things *really* work or how resilient things really are overall, stoking up panic over small things. So, go stock up on food, water and fuel, just don't do it because you fear some cyber attack on the power grid.
