What is the single best thing that military and civilian government agencies can do in their search for an all-in-one cybersecurity solution? Simple: Give up hope.

As counterintuitive as that may sound, there is no magic bullet that will solve all our cybersecurity challenges. A sufficiently-motivated and capable adversary will get around our defenses, given enough time. The question then becomes: How can we tax that motivation, or increase the cost of these attacks? What emerging areas of cybersecurity should government decision makers focus on to extend the range and capability of our deterrents?
