Bill Johnson posted a couple more links to mainframe blog posts from a
mainframe vendor-more asking the barber if you need a shave; but even ignoring
that, you don't appear to have actually read the articles, Bill.
The first one
<https://blog.syncsort.com/2018/09/mainframe/mainframes-secure-even-more-secure/>
says IBM Z is more secure because it's less common. That's not inherent security;
that's like saying your car is less vulnerable because you park it far from the
madding crowd. It may be *attacked* less, but that doesn't make it inherently more
*secure*.
No. Assuming no system is 100% secure we can assume every system has
*some* holes. The hole can be discovered by someone, however the less
people try the less likely it would happen.
Remember Navajo Indians Code Talkers?
Another example could be Linux on aunt's workstation. Aunt (uncle,
grandpa...) is not educated in computer security, however changing
Windows to Linux makes 99% of attacks impossible.
That's real life, and that kind of "obscurity" really provides security
advantage.
