The history of international cyber conflict is remarkably long and storied. The timeline of major cyber threat events stretches back nearly four decades, but it is really only the last decade that has seen the widespread proliferation of national cyber forces. As of 2007, only 10 countries had operational cyber commands, three of which were members of the NATO alliance. Just eight years later, that figure jumped to 61 nations, a full two-thirds of which were outside of the NATO alliance. Clearly, national governments have become more willing to see cybersecurity as a key responsibility. States are also cooperating and sharing the burden of securing cyberspace.
