Homeland security is a concerted national effort to prevent terrorist attacks within the US, reduce America’s vulnerability to terrorism, and minimize the damage and recover from attacks that occur. The homeland security sector was created primarily from a collection of obtainable federal agencies in response to the terrorist attacks of September 11, 2001.It was the largest government reform in 50 years. This department implied a number of government functions previously in other departments. It superseded, but did not replace the Office of Homeland Security, which retained a recommended role. It was established on November 25, 2002 by the Homeland Security Act and with approval began operating on January 24, 2003. After months of discussion about employee rights and benefits, congress passed it shortly after the midterm elections, and it was signed into law by U.S.A President George W. Bush. The department intended to strengthen U.S.A executive branch organizations associated to “homeland security” into a single cabinet agency. It was formed as a reaction to the terrorists’ attacks that occurred on September 11th, 2001. The Department of Homeland Security manages the Emergency attentiveness and Response Directorate. The directorate helps accomplish the Department’s overarching goal: to keep America safe from terrorist attacks. The Department works to enhance attentiveness and response efforts and to integrate these efforts with prevention work.
