A number of mainstream magazines and newspapers have recently published reports on the increasing threat of "cyberwarfare," the significant resources being devoted to fighting that "war" and what we're doing to protect the critical national asset that is our digital infrastructure.
Unfortunately, most of the responses (and the ones favored by the Obama administration) are focused on paying insanely large amounts of money to private contractors to create and deploy complex technological solutions in hopes of addressing the threat.
What advocates of this approach fail to appreciate is that (A) most of the actual threat comes from uneducated human operators of the technology in question, and (B) deploying homogeneous, technologically complex solutions often makes us more vulnerable, not less.
