The threats to government computer systems and networks continue to evolve and grow due to steady advances in the sophistication of attack technology, the ease of obtaining such technology, and the increasing use of these techniques by state and nonstate actors to gain intelligence and/or disrupt operations. The US Government Accountability Office (GAO) cites that from 2006 to 2012, the number of cyberincidents reported by federal agencies to the US Computer Emergency Readiness Team (US-CERT) grew from 5,503 to 48,562, an increase of 782 percent.
