Today, cyber warfare affects everyone—from governments that need to protect sensitive political and military information, to businesses small and large that stand to collectively lose trillions of dollars each year to cyber crime, to individuals whose privacy, assets, and identities are subject to intrusion and theft. The problem is monumental and growing exponentially. Encyclopedia of Cyber Warfare provides a complete overview of cyber warfare, which has been used with increasing frequency in recent years by such countries as China, Iran, Israel, North Korea, Russia, and the United States. Readers will gain an understanding of the origins and development of cyber warfare and of how it has become a major strategic element in warfare for countries throughout the world. The encyclopedia's entries cover all of the most significant cyber attacks to date, including the Stuxnet worm that successfully disabled centrifuges in Iran's Natanz uranium enrichment facility; the attack on Israel's internet infrastructure during its January 2009 military offensive in the Gaza Strip; the worldwide "Red October" cyber attack that stole information from embassies, research firms, military installations, and nuclear and other energy infrastructures; and cyber attacks on private corporations like Sony.
