Trend Micro has a very nice article talking about smart manufacturing. Robots can do the job all day without a problem knowing that they can communicate a failure within the network and stop if thre is a problem. I don’t know if this is the case, but research says that this can be broken, and if it is, it isn’t going to be very good.
If an actor were to try this, the entire platform could be told to do something else by manipulation.
I’d say lets learn what the research is teaching us, and read this forward thinking article Securing Smart Manufacturing and we’re going to have to see what plays out on this one.
