MASINT (Measurement and Signature Intelligence) uses scientific and technical methods to collect strategic and tactical intelligence. It builds models to aid decision-making but can be complicated to apply quickly. In 2004, President Bush established the Commission on Intelligence Capabilities to review intelligence functions after 9/11. The commission found 74 areas needing reform, and 71 were addressed in the 2004 Intelligence Reform and Terrorism Prevention Act. This act established a director of national intelligence and improved information sharing. MASINT now plays a role in countering global terrorism by tracking networks and using enemies' own technology against them.
