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 US 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 US homeland security enterprise.

—Janet Napolitano, US Secretary of Homeland Security (2009–2013), President, University of California, Author of How Safe Are We? Homeland Security Since 9/11

“There are essential lessons here for both civilian and military authorities to minimize risks and maximize our national defenses against enemies foreign and domestic.”
 —General Lori J Robinson, Former Commander, US Northern Command and North American Aerospace Defense Command

“This is a unique and important contribution to the much-neglected field of homeland security, and indispensable to those who want to understand where the US homeland security enterprise has been and where it needs to go in the future.”
