Installing VPN access on Windows Server 2016

Exactly.
My question, which I thought was a simple one, was that have Microsoft products been hardened sufficiently in recent years to a point where best practice in 2004 isn't the same as best practice in 2017. It seems on ML (tough crowd), merely asking the question implies I'm stupid ("do you believe that the entire concept of hacking has been solved and doesn't exist today?").
I found this blog post by Microsoft interesting and it's kind of where I was coming from
https://blogs.technet.microsoft.com/exchange/2013/07/17/life-in-a-post-tmg-world-is-it-as-scary-as-you-think/
eg "We made a lot of progress over those ten years since then. We delivered on the goal that the security of the application can be better managed inside the OS and the application rather than at the network layer."I was just asking the question because I though it might have some merit. Sorry I asked and I'll leave it now....

But the behaviour you are protecting against has not went away. You have to always continue protecting against it. As soon as you stop protecting against it, it will be attacked.
In regards to your linked article, Microsoft might have made managing the security of an application better inside the OS, but that does nothing for actually securing the application.

I think it is a dangerous question to be asked. Systems are never going to be so secure that security basics can be abandoned. There has not been and there is never expected to be some magic bullet. But suggesting that there might be is incredibly dangerous because it implies that we don't realize how serious the threats are, how they work and think that the time might come where we can ignore them. Security does not change that way.
Example: This is much like saying we no longer need door locks. That other security has improved so much that we should no longer bother locking doors. Given physical security goes back thousands of years, one thing we have no expectation of is that door locks will ever be something to be abandoned.

That's not quite what you said, though, and it's not really a reasonable thing. Hardening is not the issue, so conceptually this isn't a thing that can happen.
But more importantly, you felt that because threats were "old" (2004 is recent in security terms) that they didn't warrant immediate concern today because you perceived them as old. But that's not how systems, software and security work. Threats on our systems have been, for all intents and purposes, identical over all time. The basics of how systems work and how they get compromised have not changed, so our security needs have not changed.
That's why I mentioned that it seemed that you felt that "hackers" had gone away and can no longer access systems (that the news about the US, Russia and China doing this constantly is all faked, for example.) The threat that you perceived as old in 2004 is the one that everyone is scared of today (plus ransomware.)

No I didn't.

So what do Microsoft mean when they say:
1.We do not require traffic to be authenticated prior to hitting services in front of Exchange Online.
2.We do not do any form of pre-authentication of services in front of our corporate, on-premises messaging deployments either.
We don’t use TMG to protect ourselves any more.I'm not sure what I'm missing here. Do they run reverse proxies? What does a reverse proxy protect against, if it isn't doing pre-authentication?

Then what did you mean when you dismissed my examples of buffer overflows as being meaningless to you because they were not current enough? What else was I (am I) supposed to think since age based dismissal was the only response.

I need an example that's not from 2004!
This. What did you mean by this? Why did you need recent examples of a timeless security concept?

They don't require authentication before that point. And does TMG even exist anymore? I'd be pretty concerned if they were using that.
Reverse proxies protect against all the things that we discussed, like buffer overflow attacks, without authentication.

That's the way it's always been done?
Years ago, it was generally accepted that Microsoft products weren't very secure and that you wouldn't want to expose them. But it's 2017 now, and I'm not sure that assumption still applies.
People used to explain it to me by saying "cuz it's Microsoft, duh..". Now I need to know specifics on how an attack on an exposed MS product could play out and why.
Going back to the original question, maybe I could have answered it more clearly. Let me try it again...
- It was never because of Microsoft of MS Products
- All products, even open source ones, still have risks and always will. Software will never be perfect.
- MS is closed source so will always be an additional risk that cannot be audited on top of other things.
- I'm not sure who told you "it's MS duh" but they were wrong and I think that myth became the foundation of your thinking and you are applying it to us.
- This is basic network security and we apply it to nearly everything, including 100% non-MS web stacks like the one we are using now which passes through two reverse proxies before getting to you.

I don't remember experiencing or hearing about an MS RRAS server that was compromised or hacked do to the fault of the MS Software directly. It's always been because of dirt poor implementation and security oversights... connecting a Windows server directly to the internet, not updating OS, firmware, drivers, etc.
VPN on Windows Server 2016 works quite well and opens up a lot of nice options not available on other platforms and devices.
I guess the trick is just doing it correctly...

If you consider exposing the server as a mistake leading to compromise, that's really the point that we were making
