If you're using that analogy, then it's still a valid concern. What are the deadbolts for the connection? Can we see the failed attempts to gain access like we could with physical damage to the door? There should be some level of reasonable protection in either scenario. I feel like for many connected devices those reasonable protections are absent because most people are more ignorant about cyber security than they are about physical security, so the market isn't really adopting those protections at the scale it should.
