Beyond 9/11: Homeland Security for the Twenty-First Century

Belfer Center Studies in International Security


For Americans, the terrorist attacks of September 11, 2001, crystallized the notion of homeland security. But what does it mean to "secure the homeland" in the twenty-first century? What lessons can be drawn from the first two decades of U.S. government efforts to do so? In Beyond 9/11, leading academic experts and former senior government officials address the most salient challenges of homeland security today.

The contributors discuss counterterrorism, cybersecurity, and critical infrastructure protection; border security and immigration; transportation security; emergency management; combating transnational crime; protecting privacy in a world of increasingly intrusive government scrutiny; and managing the sprawling homeland security bureaucracy. They offer crucial strategic lessons and detailed recommendations on how to improve the U.S. homeland security enterprise
