Federal Bureau of Investigation's Ability to Address the National Security Cyber Intrusion Threat

摘要

Computer systems integral to the infrastructure, economy, and defense of the United States are under constant attack by a growing array of adversaries. For 2008, the Department of Homeland Security publicly reported 5,499 known intrusions of U.S. government computer systems alone, a 40 percent increase from 2007. Because of its statutory authority, expertise, and responsibilities for counterterrorism, counterintelligence, and criminal law enforcement duties, the FBI plays a critical role in combating cyber threats.
