Federal information systems are routinely confronted with increasingly sustained cyber attacks –
many of which involve targeted and serious threats – executed with varying levels of technical
sophistication. The number of incidents reported by Federal agencies to the Department of
Homeland Security has, in fact, increased by over 400 percent in the past 4 years. To help
combat the escalating number and complexity of cyber security threats, the Department of
Energy expended significant funds in Fiscal Year (FY) 2010 on cyber security measures
designed to protect systems and their information. The Department's systems support various
program operations, including its energy, national security, scientific discovery and innovation,
and environmental remediation portfolios.
