- dabent 14y agoThe power grid might not be connected to the internet, but, as the article points out, all it takes is someone with a thumb drive to plant malware.
- marshray 14y agoThe power companies and grid are just like everybody else with a distributed system these days: they have a lot of monitoring data and the cheapest way to backhaul it is over the commodity internet. They find VPNs useful too. True that a finely crafted USB stick can be used to bridge an air gap, but the power grid needs to not be connected to the interent. It's a protocol layering violation: the internet depends on the power grid. If the power grid also depends on the internet, what happens when one goes down for any length of time? How long would it take to get such a system turned back on again?
