&gt;Can&#x27;t be that hard..... oh, but it is.<p>No more so than securing any other piece of tech connected to the internet &amp; the same principles apply. Split it into zones like you would a corporate network &amp; stick firewalls in between to separate the fluffy online stuff from the core systems. That is ultimately where this is going - a mini network of devices on wheels.<p>And if something is really too hot to connect at all then you can always isolate that system completely.<p>Obviously its not going to be 100% fool proof but then again nothing is.
