Folks,
Why does everybody insist on overlooking the obvious ??.
The hell with how quickly you apply fixes.
Agreed.
MVS (or OS/390 or z/OS or whatever you want to call it) has
NEVER been hacked or destroyed by an ex employee !!.
How do you know?
Do you expect any financial company to make an advertisement "Hello!
We're open for hackers!". I suspect that no company want do disclose it.
In fact, let me re-state that .. the mainframes HAVE NEVER
been hacked or destroyed by an ex employee !!.
Well, I know such evidence (maybe it was misuse - it's a matter of
definition of "been hacked"), cannot provide details.
Another, publicly known example: Kevin Mitnick. Obviously he wasn't
ex-employee (is it better?), and he hacked people, not systems. So?
Some remarks:
1. "Mainframe system" could mean z/OS or poorly configured Linux. Is the
Linux on mainframe any more secure than Linux on PC? IMHO the difference
is none or very small.
2. Usually "mainframe systems" are big, very big or huge installations
when compared to PC installations. There is no reason to compare small
PC server in small company to huge financial system.
3. Ex-employees hacking, social hacking - that could affect any
platform, the platform resilience play minor role here. Again, usually
the bigger comany the better rules apply.
4. Obviously (for us, mainframers) it's much easier to set up secure
mainframe shop, that to set up secure PC installation. More, PC
installation cannot achieve the level of security which is available for
mianframe (with z/OS). It's like bank safe and tent: you can leave both
open - and security is comparable (and poor). You can also try to secure
both - then you have good effects with safe, but still poor effects with
a tent.
