Hi There are an enormous number of branches and twists in coming up with a “zero failure” system.
One of many: If the system uses GPS (or any GNSS) *and* Joe pulls up with a GPS jammer in his truck, all GPS systems go off the air. If Joe parks in the parking lot for a few weeks, the systems are all down for that period of time….. Unfortunately this sort of thing *does* happen. It may actually be more likely than some of the other sorts of failures you have on your list. If your system is something that is likely to be deliberately attacked (military drone), then it’s actually a pretty likely thing.
