The HSTA identifies major threats to the homeland, including current strategic threats, emerging or evolving threats, and threats of uncertain probability but potential high consequences. (DHS, IPG FY 2011-2015 Draft, 2008) The 2008 HSTA is a strategic assessment looking out five years. It represents the consensus judgment of the DHS Intelligence Enterprise. It assesses the major threats for which DHS must prepare and to which it may need to respond. To maximize its utility to DHS leaders, components and Federal, State and local officials, the 2008 HSTA organizes these threats into six major categories: (1) Demographic and travel security threats (2) Threats to the borders (3) Chemical, Biological, Radiological and Nuclear (CBRN) threats (4) Health security threats (5) Threats to critical infrastructure (6) Threats posed by homegrown extremism and radicalization.
