The digitized specter of cyberwar is haunting the boardrooms, barracks, and law offices of America. China’s audacious September 2007 infiltration of secure Pentagon networks and government servers in several other nations has powerfully demonstrated that cyberwar’s moment has arrived. Cybersecurity analysts have estimated that 120 different nations are working to evolve cyberwar capabilities. Most of today’s current cyberwar operations involve hackers probing civilian and military networks for vulnerabilities and restricted information, operations that focus less on disruption than recon and surveillance.
