The United States Department of Defense recognizes the use of computers and the Internet to conduct warfare in cyberspace as a threat to national security, but also as a platform for attack. As a major developed economy, the United States is highly dependent on the Internet and therefore greatly exposed to cyber attacks. At the same time, the United States has substantial capabilities in both defense and power projection thanks to comparatively advanced technology and a large military budget. Cyber warfare presents a growing threat to physical systems and infrastructures that are linked to the internet. Malicious hacking from domestic or foreign enemies remains a constant threat to the United States. In response to these growing threats, the United States has developed significant cyber capabilities.

The United States Cyber Command centralizes command of cyberspace operations, organizes existing cyber resources and synchronizes defense of U.S. military networks. It is an armed forces Unified Combatant Command.
