Sure, script kiddies and botnet builders wont care - i.e. attacks where the
individual target is low value, or where either the attacker or the attacked is
stupid.
But it's different when a skilled attacker meets a skilled defense: all the
exploits/attacks against high-value targets i've seen showed a great deal of care
taken to avoid detection.
Future trends are also clear: eventually, as more and more of our lives are lived on
the network, home boxes are becoming more and more valuable. So i think
concentrating on the psychology of the skilled attacker would not be unwise. YMMV.
Thanks,
Ingo
