DHS is publishing this PIA to explain its plan to expedite DHS’s ability to meet a critical mission need through the use of an interim manual data transfer process. Specifically, DHS has a critical mission need to perform classified queries on its unclassified data in order to identify individuals supporting the terrorist activities of: (1) the Islamic State of Iraq and the Levant (ISIL), (2) al-Qa’ida in the Arabian Peninsula (AQAP), (3) al-Nusrah Front, (4) affiliated offshoots of these groups, or (5) individuals seeking to join the Syria-Iraq conflict. (These individuals are often referred to as “foreign fighters” by the media and in public discourse.) The ability to perform classified searches of unclassified data for this uniquely time sensitive purpose will allow DHS to better identify and track foreign fighters who may seek to travel from, to, or through the United States. This type of comparison is a long-standing mission need; however, the specific threat has shortened the timeframe in which DHS must meet the need.
