Critical Infrastructure and Key Resources (CIKR) defines important sectors of the country that are important for continued operation of the nation. These are infrastructure and resources that keep the nation moving from day to day and their destruction may cause great disruption in the country. According to the Department of Homeland Security (2010) these are assets, systems, and networks, physical or virtual, that are vital to the country and their incapacitation may result to debilitating effects. They are infrastructure and resources that are of great national importance as they core to national security, public health and safety, economic growth and stability and as a way of life for Americans. They can be publicly or privately controlled but they are essential to operation of the economy and hence their protection is both the role of government and private sector as well (Moteff & Parfomak, 2004). Protecting and ensuring the continuity of these infrastructures and resources has been an important focus for the government. This has become important in this era of terrorism when terrorists are more likely to target these infrastructures and resources as a way of terrorism or to gain a chance to carry out terrorist activities. The Department of Homeland Security is charged with the mandate of assessing these infrastructure and resources and ensuring that they are well protected (Department of Homeland Security, 2010). Department of Homeland Security identifies different critical infrastructure and key resources including agriculture and food, banking and finance, chemical, commercial facilities, communications, critical manufacturing, dams, defense industrial base, emergency services, energy, government facilities, nuclear reactors, information technology, water, transportation, postal and shipping, and national monument and icons.
