But your point above:
"without installing malware on the victim host"

Although true on some level, is bogus for the purpose of this work,
as it being written makes an automatic assumption on working only
after malware is installed.

  The principle of "defence in depth" is that each security measure
adds to overall security by providing protections that continue to
operate even if other defences have been breached.

Isn't it more like combining several things which aren't
unconditionally secure by themselves, in the hope that the result is
something you can actually live with?

That would hardly qualify as "in depth".
