Page "Homeland security" Paragraph 3

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, 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.
