It's a world where techno-wizardry abounds. It's a place of unparalleled digital progress; but with that progress comes unprecedented dependence—dependence upon software and digital networks and electronic devices. It is the very nature of this dependence that presents the inherent dangers that we now see cropping up all around us. In that sense, no one is safe. The American military is a good example of this. Because it relies so heavily on digital technology, it must devote enormous budgetary resources to defending these capabilities from potential cyber-attacks. Like it or not, this is the world we have decided to build; and, because of that, nations and organizations and individuals must be on guard against the relentless threat of the hacker.
