Cyberjutsu is a revolutionary approach to information security based on authentic, formerly classified Ninja scrolls. It synthesizes today's infosec field with the tactics and techniques used by ancient Japanese ninjas – history’s original Advanced Persistent Threat (APT). Written by Ben McCarty, a former NSA developer and the U.S. Army’s first cyber warfare specialist, this essential handbook for cyber defenders draws fascinating parallels between the stealth warriors of feudal Japan and modern cybersecurity concepts, analyzing how real ninjas practiced information assurance, infiltration, and espionage requiring covert access to heavily fortified organizations.

Aimed at infosec experts and non-technical readers alike, the book teaches over a dozen ancient approaches to modern security problems. You’ll see why mapping your network like an adversary can be used to your advantage; you’ll discover the effectiveness of social-engineering techniques used by ninjas to slip into castles; and you’ll engage in “castle” thought exercises that will teach you to think like a true cyber ninja.
