The cyber threat confronting the United States is rapidly increasing as the number of actors with the tools and abilities to use computers against the United States or its interests is rising. The country’s vulnerability is escalating as the US economy and critical infrastructures become increasingly reliant on interdependent computer networks and the World Wide Web. Large scale computer attacks on US critical infrastructure and economy would have potentially devastating results.

Cyber threats fall into two distinct categories: threats affecting national security that emerged with Internet technology, such as cyber terrorism, foreign-based computer intrusions and cyber theft of sensitive data; and traditional criminal activity facilitated by computers and the Internet, such as theft of intellectual property, online sexual exploitation of children, and Internet fraud.
