What it Does: The Department of Homeland Security is responsible for ensuring the safety and security of the United States from both man-made and natural disasters. Created in the aftermath of the Sept. 11 terrorist attacks, DHS has largely focused on federal preparations to deal with terrorism while managing other duties related to border security, customs and emergency management, among others.
A visit to the DHS web site clearly demonstrates that the department is still fixated on terrorism. Some of DHS’ high-profile programs include:
- Constellation/Automated Critical Asset Management System (C/ACAMS), which is designed to help state and local governments better protect key infrastructure from terrorist attacks.
- Homeland Security Advisory System, which warns public safety and other government officials of potential dangers or threats to their part of the country.
- Homeland Security Information Network (HSIN), which works in tandem with the Homeland Security Advisory System to relate terrorism dangers to all 50 states, five territories, Washington, DC and 50 major urban areas.
- State & Local Fusion Centers, which allow state and local officials to combine law enforcement data and terrorism intelligence into a system designed to warn of possible terrorist threats.
- Protected Critical Infrastructure Information (PCII) Program, which duplicates some of the C/ACAMS efforts to protect private sector and pubic sector infrastructure, such as buildings, dams and power plants.
- Homeland Security Advanced Research Project Agency, which is modeled after DARPA (the Defense Advanced Research Project Agency) by funding technological research that can help mitigate the dangers of terrorism and other duties performed by law enforcement agencies.
Directorate for Science and Technology: The S&T Directorate is responsible for a variety of tasks designed to protect the country from chemical, biological, radiological, nuclear and explosive (CBRNE) attacks. It provides research, resources and technology to federal, state, local and tribal officials, emergency personnel, Border Patrol Agents, Federal Air Marshals and airport baggage screeners in order for them to handle CBRNE attacks. Examples of what S&T does are developing new technology that improves security for borders and waterways, creating advanced surveillance techniques and countermeasures and developing cyber security tools for protecting the Internet.
Domestic Nuclear Detection Office: DNDO is responsible for developing high-tech screening methods, or “architecture” as DNDO calls it, that can detect a nuclear weapon or dirty bomb entering the US through a seaport, airport or border crossing. DNDO finances the creation of radiation detection equipment and tests its effectiveness before providing it to customs officials, border guards and Coast Guard sailors. DNDO is a joint operation made up of DHS personnel and officials from the departments of Defense, Energy and State, the FBI, Nuclear Regulatory Commission, Customs and Border Protection, the Transportation Safety Administration and the US Coast Guard.
Federal Emergency Management Agency: FEMA is responsible for coordinating the federal government’s response to natural and man-made disasters. FEMA is charged with providing help to local and state governments and residents both immediately following a disaster and in the longer term. It also conducts programs to help prepare for disasters. The kinds of assistance FEMA provides ranges from advising on building codes and flood plain management to helping equip local and state emergency agencies to coordinating the federal response to a disaster. Throughout its almost 30-year history, FEMA has been synonymous with the word “disaster.” Not only is this because of the agency’s mission to assist in times of crisis, but also due to its long record of mistakes and, in some cases, failures that have exacerbated suffering caused by storms, fires or earthquakes.
Federal Law Enforcement Training Center: FLETC is the largest training program of its kind in the country, providing teaching and vocational instruction to a wide range of law enforcement and security personnel at the federal, state and local government level. Graduating approximately 50,000 students annually, FLETC helps to train officers and agents from more than 80 federal agencies, as well as numerous state and local governments. The center also trains international police in selected advanced programs. Approximately one-third of the instructors at FLETC are permanent staff. The remaining instructors are federal officers and investigators on short-term assignment from their parent organizations or recently retired from the field. Training programs offered by FLETC vary from core instruction required by many government agencies to highly specialized training for select security officials.
Office of Infrastructure Protection: OIP helps secure key buildings and other structures across the United States from terrorist attack. OIP is not directly responsible for guarding private and public infrastructure but rather is tasked with identifying important locations and assessing their vulnerability to attack or other dangers, such as natural disasters. The office catalogs buildings, dams, manufacturing plants, waterways, roads and other critical infrastructures/key resources. This effort was widely criticized in 2006 when it was revealed that OIP’s database was filled with non-critical sites, including an Amish popcorn farm and a Krispy Kreme Doughnuts drive-through in Iowa.
Office of Intelligence and Analysis: OIA serves as the intelligence wing of DHS, gathering intelligence from other government and non-government sources on potential threats to US domestic security. OIA works with members of the Intelligence Community, as well as state, local, federal and private officials, to carry out its mission. Not only does OIA gather information from these sources but it also shares intelligence it has compiled in order to warn other sectors of the government about impending threats to the nation’s security. These information-sharing activities have raised concerns among civil libertarians, as have other facets of OIA’s work.
Transportation Security Administration: TSA is an agency responsible for protecting the nation’s transportation networks from attack. Specifically, it safeguards airports and airplanes, mass-transit systems, highways, seaports, railroads and buses. Americans are most familiar with TSA personnel who man security checkpoints at airports throughout the country. During its brief existence, TSA has been inundated with charges of ineptitude and corruption.
Immigration and Customs Enforcement: ICE is not only one of the largest offices in DHS but also represents the second largest law enforcement organization in the United States, behind only the FBI. ICE enforces both immigration and customs laws, which involves going after illegal immigrants in US territory, employers who hire illegal immigrants and those trying to smuggle goods or contraband into the country. Another priority for ICE is to prevent terrorist groups and hostile nations from illegally obtaining US military weapons and sensitive technology, including weapons of mass destruction components.
US Citizenship and Immigration Services: USCIS handles all matters pertaining to immigration and the granting of citizenship to non-nationals, having taken over the responsibilities of the former Immigration and Naturalization Service. The agency decides who is eligible for lawful permanent residence in the US, which involves the granting of “green cards.” The office provides information on becoming a permanent resident, eligibility requirements and application procedures. USCIS awards an average of one million green cards, 700,000 naturalizations and one million temporary work permits each year.
US Customs and Border Protection: CBP manages, controls and protects the nation’s border in an effort to thwart terrorist attacks, while facilitating legitimate trade and travel. In addition to targeting terrorists, CBP searches for drugs, illegal immigrants, traffickers, prohibited agricultural products and counterfeit goods. CBP is made up of personnel who were formerly with the US Customs Service, Immigration and Naturalization, Animal and Plant Health Inspection Service and the entire US Border Patrol.
US Coast Guar: The Coast Guard is one of the five branches of the US Armed Services. It performs a variety of functions at US ports, coasts and inland waterways, as well as in international waters. Peacetime roles include patrolling borders, enforcing licenses, protecting the environment, maintaining waterways, conducting rescue operations, inspecting vessels for safety and stemming the flow of drugs and other contraband into the United States. In times of war, the Coast Guard can be called upon to augment the other military services.
US Secret Service: The Secret Service performs a dual mission of investigating financial crimes and providing protection for the president, vice president, their families and other political figures, both US and foreign. Criminal investigations covered by the Secret Service include computer and telecom fraud, identity theft and financial institution fraud. More recently, investigations have included computer-based attacks on the nation’s financial and informational infrastructure.
