The 9/11 terrorist attack is arguably the most famous act of terrorism in history. This event changed the worlds view about the security of the United States. More importantly the attack brought into the question safety of U.S. citizen’s safety within the borders of their own country and the need for domestic security.

Prior to this deadly attack most Americans had no experience with terrorist attack within the nation’s borders. In fact, most government agencies, especially local and domestically focused agencies had little to no experience with terrorist attacks. Attacks were seen as things that happened elsewhere in other countries. The closest information or experience that Americans and government employees with terrorist attacks prior the 9/11 tragedy were the unique airplane hijackings that occurred in the 1970s and 1980s. Consequently, American were not prepared for the 9/11 Attacks and were taken by surprise.

This paper discusses the events that led to the 9/11 Attacks, the government response to the attacks, the changes made as a result of the attacks, including the creation of the Department of Homeland Security, and the most important lesson to be taken from the attacks -- be vigilant and do not be complacent. Taking that lesson into account, a brief discussion on cyber security needs concludes this paper.
