There is no such thing as perfect security.

[Qantourisc]

Sure there is. An application/computer doesn't has to be insecure to work. It's just very hard to make no mistakes in complex machines and software.

You can always turn the device off.

It really is a matter of features and how they're implemented.

Good luck picking a byte that can exploit a 7400.

If we're only talking about exploiting a device across a network, sure turn it off or disconnect it from the network. But there's more to security than that.

One can always take the device and turn it on for oneself.

If one can't exploit the device, one can resort to rubber-hose cryptanalysis.

We are only talking about exploiting a device across a network.

Then bridge the gap by infecting pendrives. That's how e.g. Stuxnet worked.

I don't understand what you're replying to. Physical access is a great way to bypass network security, but it has nothing to do with websites.

"Exploiting device across network".

Security doesn't exist in isolation. AKA. there's always a way.
