>> I don’t think all decades old software necessarily needs to be uprooted and replaced because it’s old, so long as it’s functional. I'd say that's especially true in places like power plants. The old stuff is impossible to hack remotely because it's not on any networks. The rush to put everything on the network has made these types of systems vulnerable and places are only now trying to figure out how to secure them.
