Establishing perfect protection is impossible, but getting very good protection is trivial and accomplished by using simple to use software. That is, if you know what you’re doing. I admit that is a very special kind of trivial.
It is many things, but trivial is definitely not one of them.
As a related example, consider Bruce Schneier’s opinion that it is non-trivial to maintain as simple a thing as an air gap.
