Re: S IP mple gix
I disagree with your oversimplification of the problem. Much (but not all) of this data isn't "on the internet". It is protected by firewalls. However, if an employee (or other account with appropriate access) is breached, then data can be 'exfiltrated' via the internet.
I'm sure that companies like Boeing aren't hanging QNAP's on the internet...
And that exception "but not all" has to deal with email. There is a lot of sensitive data that we pass through email and is stored in our inbox and sent box that's hanging off the internet for any opportunistic hacker.
