Can you guess which of the following groups, offices, and councils are part of the Department of Homeland Security (DHS)? The Homeland Security Council. The Office of the Coordinator for Counterterrorism. The Chemical Emergency Preparedness and Prevention Office. The Terrorist Threat Integration Center. The Homeland Security Advisory Council. The answer is the Homeland Security Advisory Council, but don't feel too bad if you were wrong (the others, respectively, are under the White House, the State Department, the Environmental Protection Agency, and the Central Intelligence Agency). The creation of the DHS centralized many functions related to terrorism and homeland security, but others remain in separate departments. Security professionals who would like to understand these various functions and how they fit together may want to get the Homeland Security Deskbook, a looseleaf volume by the attorneys at Venable LLP that explains the organization of homeland security functions both within and outside the DHS.
