maybe not relevant here but my first thought to your question out of context is scale. My house can be easy entered by anyone determined to enter it. They can bust the door down, break the windows, crash a vehicle into it. And yet, almost no one is actually trying to get into my house. Conversely, 1000s of people and possibly hundreds of thousands of bots are trying to break into any software they can that is exposed on the internet (or possibly exposed in other ways like I have no idea if every app on my PC/Mac/Phone/Tablet is scanning my network for devices with known exploits) So, the security of my house (at least where I live) does not have to be so resilient but the security of much of my software does. https://www.youtube.com/watch?v=VPBH1eW28mo https://www.youtube.com/watch?v=VPBH1eW28mo
