> A network is as strong as the weakest link.
Depends on how you look at it. We have end-to-end security with things like https, so we don't need to worry about the links in the middle.
The BeyondCorp strategy. It also means that network and endpoints can be off the shelf. Big fan of this strategy.
Yes, and it's already the default in consumer electronics.
That's also why I don't get all the pearl clutching over dodgy unencrypted wifi: if your security relies on your wifi operator being nice, you are doing it wrong.
The main thing encrypting wifi does (or rather should do..) for you is keeping your neighbours from stealing all your bandwidth.
