Cyberwarfare has long since moved beyond the imaginations of Hollywood producers and science fiction aficionados. Countries, corporate entities, rogue states and motivated hackers are all online and actively testing the defenses of networks. Understanding how automated cyberwarfare works and how to defend against coordinated cyberattacks has become critical to the national defense interest. Researchers at Sandia National Laboratories have been mapping out attacks against large-scale computer networks to develop massive cyberattack simulations. Their work could impact the cybersecurity industry by enhancing security defense mechanisms.
