That's a great way of saying "host based security". With mobile
Internet devices (smart phones, laptops (which outsold desktops last
year apparently) etc.) becoming the dominant Internet access device, I
think host based firewalling will become the primary "firewalling"
mechanism. Network located firewalls will perform a secondary and
assistant role, because hosts can't be sure they're there when the
hosts have wired, wifi, bluetooth etc. interfaces that can all be
actively connected to the Internet at the same time.
