A letter report issued by the Government Accountability Office with an abstract that begins "Threats to systems supporting critical infrastructure and federal operations are evolving and growing. Federal agencies have reported increasing numbers of cybersecurity incidents that have placed sensitive information at risk, with potentially serious impacts on federal and military operations; critical infrastructure; and the confidentiality, integrity, and availability of sensitive government, private sector, and personal information. The increasing risks are demonstrated by the dramatic increase in reports of security incidents, the ease of obtaining and using hacking tools, and steady advances in the sophistication and effectiveness of attack technology. The number of incidents reported by federal agencies to the U.S. Computer Emergency Readiness Team has increased 782 percent from 2006 to 2012."
