It's also a non-standard OS, with a very specific kernel - so commonly known hacking techniques would probably not work. I imagine that the kind of people who tried to hack it were "script kiddies" - using generic, buffer-overflow type scenarios. Like it says in the article, "Proper" hackers (i.e. people that know what they're doing) are unlikely to try.
 
Also, there is no such thing as an invulnerable OS, because you can never imagine all the types of attack an OS may come under...

I agree, this is definitely the way forward - I think we'll start to see a move away from big, catch-all operating systems (which are now becoming too large to manage properly and securely, no matter how well you train your programmers) towards smaller, more specific OSs - which, because they're smaller, will be easier to manage, and easier to ensure that they're bug-free and secure.

This isn't the future for most of us
 
Too expexsive and propietary.
 
 
I think you will see NOS's that are modular
 
You basically install only whats needed for your orgaization and nothing more.
 
 
So instead of having a server with everything installed you your web server you only have the web server part, and everything else removed.
 
And so on with other services.
 
THe day of having a Server be all things at once is coming to an end though, unless your a small business.

the ONLY none hackable server is one that is not connected to the internet!!!
 
 
period - end of story - if it can be made, it can be broke.
