Report: Information Sharing for Homeland Security - A Brief Overview

After the events of 09/11/2001, many suggestions were made to improve information sharing among US government agencies at all levels, the US private sector, and certain foreign governments. The types of information potentially available for sharing includes raw data (no assessement of accuracy), knowledge (high degree of validity or reliability), and finished intelligence (source reliability and information qualitatively evaluated).

On January 10, 2005, The Library of Congress, Congressional Research Service, released an updated report for Congress entitled Information Sharing for Homeland Security: A Brief Overview. This report reviews some existing homeland security information sharing arrangements, some projected arrangements, and discusses related policy, evaluations, and proposed legislation.
