Although there is a federal Department of Homeland Security, it is neither solely dedicated to homeland security missions, nor is it the only part of the federal government with significant responsibilities in this arena. Although DHS does include many of the homeland security functions of the federal government, several of these functions or parts of these functions remain at their original executive branch agencies and departments, including the Departments of Justice, State, Defense, and Transportation. 110-53 ):
Counterterrorism and Security Management, Border Security and Trade, Immigration, and Disaster Preparedness, Response, and Recovery. In many cases, a specific CRS report is highlighted as a source of more detailed information. The issues included in this report do not represent a comprehensive list of possible issues—they represent a broad array of issues likely to be addressed by Congress in the coming months. Twelve years after the 9/11 terrorist attacks, policy makers continue to debate the definition of homeland security. The threat was brought into the spotlight by the November 2002 attack on a chartered Israeli airliner in Mombasa, Kenya. Some Members of Congress have raised questions about whether DHS's investments at the border have been effective, and some have argued that enforcement has been compromised by the fact that DHS does not have a single, overarching strategy for border security.

From the establishment of the Department of Homeland Security (DHS) in January 2003 through 2007, the President and the Secretary of Homeland Security used provisions of the Homeland Security Act of 2002, most notably Section 872, to implement a number of major and minor departmental reorganizations. Current initiatives in each of these areas are discussed below.
With the 10th anniversary of the establishment of the Department of Homeland Security (DHS), many observers have made a fresh assessment of where America's homeland security enterprise stands today. DHS is currently the third-largest department in the federal government, although it does not incorporate all of the homeland security functions at the federal level. The definition of homeland security remains unsettled, and questions about the effectiveness and efficiency of the department have been raised since it was first proposed. Evolution of America's response to terrorist threats has continued under the leadership of different Administrations, Congresses, and in a shifting environment of public opinion.
This report outlines an array of homeland security issues that may come before the 113th Congress. After a brief discussion of the overall homeland security budget, the report divides the specific issues into five broad categories:
Counterterrorism and Security Management, Border Security and Trade, Immigration, Disaster Preparedness, Response, and Recovery, and Departmental Management.
Each of those areas contains a survey of topics briefly analyzed by Congressional Research Service experts. The information included only scratches the surface on most of these issues. More detailed information can be obtained by consulting the CRS reports referenced herein, or by contacting the relevant CRS expert.
