The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security, initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle Columbia in the 2003 return-flight disaster.
Executive Order 12148 was an executive order enacted by President Jimmy Carter on July 20, 1979 to transfer and reassign duties to the newly formed agency, known as the Federal Emergency Management Agency (FEMA), created by Executive Order 12127. The order combined several federal agencies tasked with emergency preparedness and civil defense spread across the executive departments into a unified entity that was established as an independent agency, free of Cabinet interference, with authority as the lead federal agency in a presidentially-declared disaster.

Emergency management software is the software used by local, state and federal emergency management personnel to deal with a wide range of disasters and can take many forms. For example, training software such as simulators are often used to help prepare first responders, word processors can keep form templates handy for printing and analytical software can be used to perform post-hoc examinations of the data captured during an incident. All of these systems are interrelated, as the results of an after-incident analysis can then be used to program training software to better prepare for a similar situation in the future. Crisis Information Management Software (CIMS) is the software found in emergency management operation centers (EOC) that supports the management of crisis information and the corresponding response by public safety agencies.
Homeland Security Grant Program (HSGP) is a program in the United States established in 2003 and was designated to incorporate all projects that provide funding to local, state, and Federal government agencies by the Department of Homeland Security. The purpose of the grants is to purchase surveillance equipment, weapons, and advanced training for law enforcement personnel in order to heighten security. The HSGP helps fulfill one of the core missions of the Department of Homeland Security by enhancing the country's ability to prepare for, prevent, respond to and recover from potential attacks and other hazards. The HSGP is one of the main mechanisms in funding the creation and maintenance of national preparedness, which refers to the establishment of plans, procedures, policies, training, and equipment at the Federal, State, and local level that is needed to maximize the ability to prevent, respond to, and recover from major events such as terrorist attacks, major disasters, and other emergencies. The HSGP's creation stemmed from the consolidation of six original projects that were previously funded by the Office of State and Local Government Coordination and Preparedness. The HSGP now encompasses five projects in the program: State Homeland Security Program, Urban Areas Security Initiative, Operation Stonegarden, Metropolitan Medical Response System Program, and Citizen Corps Program. During the 2010 fiscal year, the Department of Homeland Security will spend $1,786,359,956 on the Homeland Security Grant Program.
