Homeland security is difficult to define because it means something different to each agency. The general idea behind homeland security is to protect the country not only from terrorist attacks, but also from natural disasters and other disasters that may arise. Homeland security places an emphasis on interagency communication to prevent a disaster, and, if need be, handle disaster response. Homeland security pervades all levels and agencies of the government.
