Actually I work on software that’s used by almost every bank in America. It’s not an attitude, it’s REALITY. Like I explained in the part you didn’t bother to quote:
Anything that can be done legitimately
can be done illegitimately
That’s a simple fact everybody in the IT world understands.
“Anything that can be done legitimately
can be done illegitimately”
In theory, yes.
In the real world, you would want to shrink the possibility to as close to zero as you practically can.
