The reality of the homeland security enterprise Information Sharing Environment

Responding to recommendations from the 9/11 Commission, Congress created the Information Sharing Environment (ISE) with the passage of the 2004 Intelligence Reform and Terrorism Prevention Act. Linked to the creation of the Office of the Director of National Intelligence and championed by that office's program manager for the ISE, the ISE has contributed to national intelligence reform by attempting to improve information sharing across the federal, state, local, territorial, and tribal domains. Given the rise in domestic terrorist attacks and the progress of intelligence reform over the last 16 years, this thesis explores an analysis of the ISE's effectiveness and an examination of alternative means of information sharing to address the remaining information-sharing challenges brought to light in attacks carried out between 2014 and 2017. Alternative information-sharing techniques have been used by our nation's special operations forces and by our largest police force, the New York Police Department. The best practices of organizations such as these may be leveraged by the ISE to further future intelligence-sharing reform.
