This requires communications networks that provide information-sharing capabilities between the various levels of government--federal, state, and local. GAO's objective was to identify and describe, through agency reporting, major networks and examples of applications that the agencies considered important in supporting their homeland security functions. (For purposes of this review, GAO defined networks as "the data communication links that enable computer systems to communicate with each other.") GAO corroborated agency-provided information about networks used by multiple agencies. While agencies verified the accuracy of the data about their networks, GAO cannot ensure that agencies provided data on all applicable networks. In commenting on a draft of this report, seven of the nine agencies generally concurred with the facts contained in this report. Technical comments were incorporated as appropriate. Two agencies declined to comment. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-04-375/html/GAOREPORTS-GAO-04-375.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-04-375/pdf/GAOREPORTS-GAO-04-375.pdf GAO-04-375 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-04-375 Other Written Product GAO-04-375; Information Technology: Major Federal Networks That Support Homeland Security Functions; Counterterrorism Domestic intelligence Emergency preparedness Government information dissemination Information technology National defense operations National preparedness Homeland security
