Cybersecurity: DHS Needs to Enhance Efforts to Improve and Promote the Security of Federal and Private-Sector Networks, Testimony Before the Committee on Homeland Security and Governmental Affairs, U.S. Senate [open pdf - 267KB]
"The emergence of increasingly sophisticated threats and continuous reporting of cyber incidents underscores the continuing and urgent need for effective information security. GAO (Government Accountability Office) first designated information security as a government-wide high- risk area in 1997. GAO expanded the high-risk area to include the protection of cyber critical infrastructure in 2003 and protecting the privacy of personally identifiable information in 2015. Federal law and policy provide DHS with broad authorities to improve and promote cybersecurity. DHS (Department of Homeland Security) plays a key role in strengthening the cybersecurity posture of the federal government and promoting cybersecurity of systems supporting the nation's critical infrastructures."
