The United States Department of Homeland Security (DHS) is a cabinet department of the United States federal government, created in response to the September 11 attacks, and with the primary responsibilities of protecting the United States of America and U.S. Territories (including Protectorates)^[vague] from and responding to terrorist attacks, man-made accidents, and natural disasters. In fiscal year 2011 it was allocated a budget of $98.8 billion and spent, net, $66.4 billion.

Where the Department of Defense is charged with military actions abroad, the Department of Homeland Security works in the civilian sphere to protect the United States within, at, and outside its borders. Its stated goal is to prepare for, prevent, and respond to domestic emergencies, particularly terrorism. On March 1, 2003, DHS absorbed the Immigration and Naturalization Service and assumed its duties. In doing so, it divided the enforcement and services functions into two separate and new agencies: Immigration and Customs Enforcement and Citizenship and Immigration Services. The investigative divisions and intelligence gathering units of the INS and Customs Service were merged forming Homeland Security Investigations. Additionally, the border enforcement functions of the INS, including the U.S. Border Patrol, the U.S. Customs Service, and the Animal and Plant Health Inspection Service were consolidated into a new agency under DHS: U.S. Customs and Border Protection. The Federal Protective Service falls under the National Protection and Programs Directorate.

Homeland security is an umbrella term for security efforts to protect states against terrorist activity.^{[citation needed]} Specifically, is a concerted national effort to prevent terrorist attacks within the U.S., reduce America’s vulnerability to terrorism, and minimize the damage and recover from attacks that do occur.

The term arose following a reorganization of many U.S. government agencies in 2003 to form the United States Department of Homeland Security after the September 11 attacks, and may be used to refer to the actions of that department, the United States Senate Committee on Homeland Security and Governmental Affairs, or the United States House of Representatives Committee on Homeland Security.

Homeland defense (HD) is the protection of U.S. territory, sovereignty, domestic population, and critical infrastructure against external threats and aggression. (Definition will be incorporated into JP 3-26[1] upon its approval).[2] Not to be confused with Homeland security.

In the United States, the concept of "Homeland Security"extends and recombines responsibilities of government agencies and entities. According to Homeland security research, the U.S. federal Homeland Security and Homeland Defense includes 187 federal agencies and departments, including the United States National Guard, the Federal Emergency Management Agency, the United States Coast Guard, U.S. Customs and Border Protection, U.S. Immigration and Customs Enforcement, United States Citizenship and Immigration Services, the United States Secret Service, the Transportation Security Administration, the 14 agencies that constitute the U.S. intelligence community and Civil Air Patrol. Although many businesses now operate in the area of homeland security, it is overwhelmingly a government function.

Brittany Murphy was born as Brittany Anne Bertolotti in Atlanta, Georgia, on November 10, 1977. Her parents, Sharon Kathleen Murphy and Angelo Joseph Bertolotti, divorced when she was two years old, and Murphy was raised by her mother in Edison, New Jersey, where she attended Edison High School. Bertolotti was so estranged from the family that he was not named as the father on the first death certificate. The family later moved to Los Angeles so that Murphy could pursue an acting career. Murphy said her mother never tried to stifle her creativity, and she considered her mother a crucial factor in her later success: "When I asked my mom to move to California, she sold everything and moved out here for me. ... She always believed in me." Murphy's mother is of Irish and Eastern European descent and her father is Italian American. She was raised a Baptist and later became a non-denominational Christian.
