The attacks were a direct or indirect cause of massive changes in United States domestic policy.  Most notably, the ''Homeland Security Act of 2002'' "established a [[Department of Homeland Security]], as an executive department of the United States" <ref>[http://www.whitehouse.gov/deptofhomeland/bill/hsl-bill.pdf H.R. 5005 The Homeland Security Act]</ref>, a cabinet level position.  One of the tools implemented by the Department is the [[Homeland Security Advisory System]], a color coded advisory system meant to "establish a comprehensive and effective means to disseminate information regarding the risk of terrorist acts to Federal, State, and local authorities and to the American people." <ref>[http://www.dhs.gov/xinfoshare/laws/ DHS Laws and Regulations] Department of Homeland Security</ref>
