I'm open to different terminology, but I think you are changing the meaning
here. Opening and chink seem to me like vulnerability, and so would not
stand alone to help define vulnerability. Perhaps "action" would replace
attack. So, when you perform action(s) X you get outcome Y. X and Y define
the vulnerability. This might help make more explicit that we're talking
about what is done, not how. So for example we don't care which program you
used to send the nasty packet, but nasty packet + blue screen = ping of death.

I see value in different levels of abstraction, including possible other
approaches that we have not yet invented or discussed yet. But I don't think
that _we_ have to manage that. It should be the province of vulnerability
databases that use other layers of abstraction to encode that type of

Right. So lets only tackle one hard problem, not two. But even more to the
point, would it serve our primary purposes for us to add this complexity vs.
only having "same attack" be the method?
