The United States Department of Homeland Security (DHS) is a cabinet department of the United States federal government with responsibilities in public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management.  It was created in response to the September 11 attacks, and is currently the youngest U.S. cabinet department.
In fiscal year 2017, it was allocated a net discretionary budget of $40.6 billion.  With more than 240,000 employees,  DHS is the third largest Cabinet department, after the Departments of Defense and Veterans Affairs.  Homeland security policy is coordinated at the White House by the Homeland Security Council. Other agencies with significant homeland security responsibilities include the Departments of Health and Human Services, Justice, and Energy.
Whereas the Department of Defense is charged with military actions abroad, the Department of Homeland Security works in the civilian sphere to protect the United States within, at, and outside its borders. Its stated goal is to prepare for, prevent, and respond to domestic emergencies, particularly terrorism.  On March 1, 2003, DHS absorbed the Immigration and Naturalization Service (INS) and assumed its duties. In doing so, it divided the enforcement and services functions into two separate and new agencies: Immigration and Customs Enforcement and Citizenship and Immigration Services. The investigative divisions and intelligence gathering units of the INS and Customs Service were merged forming Homeland Security Investigations. Additionally, the border enforcement functions of the INS, including the U.S. Border Patrol, the U.S. Customs Service, and the Animal and Plant Health Inspection Service were consolidated into a new agency under DHS: U.S. Customs and Border Protection. The Federal Protective Service falls under the National Protection and Programs Directorate.

In an August 5, 2002 speech, President Bush said: "We're fighting ... to secure freedom in the homeland."  Prior to the creation of DHS, American presidents had referred to the U.S. as "the nation" or "the republic", and to its internal policies as "domestic". Also unprecedented was the use, from 2002, of the phrase "the homeland" by White House spokespeople.
National Terrorism Advisory System
In 2011, the Department of Homeland Security phased out the old Homeland Security Advisory System, replacing it with a two-level National Terrorism Advisory System. The system has two types of advisories: Alerts and Bulletins. NTAS Bulletins permit the Secretary to communicate critical terrorism information that, while not necessarily indicative of a specific threat against the United States, can reach homeland security partners or the public quickly, thereby allowing recipients to implement necessary protective measures. Alerts are issued when there is specific and credible information of a terrorist threat against the United States. Alerts themselves have two levels: Elevated and Imminent. An Elevated Alert is issued when there is credible information about an attack but only general information about timing or a target. An Imminent Alert is issued when the threat is very specific and impending in the very near term.
On March 12, 2002, the Homeland Security Advisory System, a color-coded terrorism risk advisory scale, was created as the result of a Presidential Directive to provide 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." Many procedures at government facilities are tied into the alert level; for example a facility may search all entering vehicles when the alert is above a certain level. Since January 2003, it has been administered in coordination with DHS; it has also been the target of frequent jokes and ridicule on the part of the administration's detractors about its ineffectiveness. After resigning, Tom Ridge stated that he did not always agree with the threat level adjustments pushed by other government agencies. 
In January 2003, the office was merged into the Department of Homeland Security and the White House Homeland Security Council, both of which were created by the Homeland Security Act of 2002. The Homeland Security Council, similar in nature to the National Security Council, retains a policy coordination and advisory role and is led by the Assistant to the President for Homeland Security. 
As of 13 January 2011, the DHS advised the American public of an 'elevated national threat' level, recommending that all Americans 'should establish an emergency preparedness kit and emergency plan for themselves and their family, and stay informed about what to do during an emergency'. 
In response to the September 11 attacks, President George W. Bush announced the establishment of the Office of Homeland Security (OHS) to coordinate "homeland security" efforts. The office was headed by former Pennsylvania Governor Tom Ridge, who assumed the title of Assistant to the President for Homeland Security. The official announcement stated:
|“||The mission of the Office will be to develop and coordinate the implementation of a comprehensive national strategy to secure the United States from terrorist threats or attacks. The Office will coordinate the executive branch's efforts to detect, prepare for, prevent, protect against, respond to, and recover from terrorist attacks within the United States. ||”|
Ridge began his duties as OHS director on October 8, 2001.
According to Peter Andreas, a border theorist, the creation of DHS constituted the most significant government reorganization since the Cold War, and the most substantial reorganization of federal agencies since the National Security Act of 1947, which placed the different military departments under a secretary of defense and created the National Security Council and Central Intelligence Agency. DHS also constitutes the most diverse merger of federal functions and responsibilities, incorporating 22 government agencies into a single organization. 
The Department of Homeland Security was established on November 25, 2002, by the Homeland Security Act of 2002. It was intended to consolidate U.S. executive branch organizations related to " homeland security " into a single Cabinet agency. The following 22 agencies were incorporated into the new department: 
|Original agency||Original department||New agency or office after transfer|
|U.S. Customs Service||Treasury||U.S. Customs and Border Protection U.S. Immigration and Customs Enforcement|
|Immigration and Naturalization Service||Justice||U.S. Customs and Border Protection U.S. Immigration and Customs Enforcement U.S. Citizenship and Immigration Services|
|Federal Protective Service||General Services Administration||National Protection and Programs Directorate|
|Transportation Security Administration||Transportation||Transportation Security Administration|
|Federal Law Enforcement Training Center||Treasury||Federal Law Enforcement Training Center|
|Animal and Plant Health Inspection Service (part)||Agriculture||U.S. Customs and Border Protection|
|Office for Domestic Preparedness||Justice||Responsibilities distributed within FEMA|
|Federal Emergency Management Agency||none||Federal Emergency Management Agency (FEMA)|
|Strategic National Stockpile National Disaster Medical System||Health and Human Services||Returned to HHS, July, 2004|
|Nuclear Incident Response Team||Energy||Responsibilities distributed within FEMA|

|Energy Security and Assurance Program||Energy||Office of Infrastructure Protection|
|U.S. Coast Guard||Transportation||U.S. Coast Guard|
|U.S. Secret Service||Treasury||U.S. Secret Service|
Prior to the signing of the bill, controversy about its adoption centered on whether the Federal Bureau of Investigation and the Central Intelligence Agency should be incorporated in part or in whole (neither were included). The bill was also controversial for the presence of unrelated " riders ", as well as for eliminating certain union-friendly civil service and labor protections for department employees. Without these protections, employees could be expeditiously reassigned or dismissed on grounds of security, incompetence or insubordination, and DHS would not be required to notify their union representatives.
The plan stripped 180,000 government employees of their union rights.  In 2002, Bush officials argued that the September 11 attacks made the proposed elimination of employee protections imperative. 
Congress ultimately passed the Homeland Security Act of 2002 without the union-friendly measures, and President Bush signed the bill into law on November 25, 2002. It was the largest U.S. government reorganization in the 50 years since the United States Department of Defense was created.
Tom Ridge was named secretary on January 24, 2003 and began naming his chief deputies. DHS officially began operations on January 24, 2003, but most of the department's component agencies were not transferred into the new Department until March 1. 
After establishing the basic structure of DHS and working to integrate its components and get the department functioning, Ridge announced his resignation on November 30, 2004, following the re-election of President Bush. Bush initially nominated former New York City Police Department commissioner Bernard Kerik as his successor, but on December 10, Kerik withdrew his nomination, citing personal reasons and saying it "would not be in the best interests" of the country for him to pursue the post.
Changes under Michael Chertoff
On January 11, 2005, President Bush nominated federal judge Michael Chertoff to succeed Ridge. Chertoff was confirmed on February 15, 2005, by a vote of 98–0 in the U.S. Senate. He was sworn in the same day. 
In February 2005, DHS and the Office of Personnel Management issued rules relating to employee pay and discipline for a new personnel system named MaxHR. The Washington Post said that the rules would allow DHS "to override any provision in a union contract by issuing a department-wide directive" and would make it "difficult, if not impossible, for unions to negotiate over arrangements for staffing, deployments, technology and other workplace matters." 
In August 2005, U.S. District Judge Rosemary M. Collyer blocked the plan on the grounds that it did not ensure collective-bargaining rights for DHS employees. 
A federal appeals court ruled against DHS in 2006; pending a final resolution to the litigation, Congress's fiscal year 2008 appropriations bill for DHS provided no funding for the proposed new personnel system.  DHS announced in early 2007 that it was retooling its pay and performance system and retiring the name "MaxHR". 
In a February 2008 court filing, DHS said that it would no longer pursue the new rules, and that it would abide by the existing civil service labor-management procedures. A federal court issued an order closing the case. 
A DHS press release dated June 6, 2003  explains the seal as follows:
The seal is symbolic of the Department's mission – to prevent attacks and protect Americans – on the land, in the sea and in the air. In the center of the seal, a graphically styled white American eagle appears in a circular blue field. The eagle's outstretched wings break through an inner red ring into an outer white ring that contains the words "U.S. DEPARTMENT OF" in the top half and "HOMELAND SECURITY" in the bottom half in a circular placement. The eagle's wings break through the inner circle into the outer ring to suggest that the Department of Homeland Security will break through traditional bureaucracy and perform government functions differently. In the tradition of the Great Seal of the United States, the eagle's talon on the left holds an olive branch with 13 leaves and 13 seeds while the eagle's talon on the right grasps 13 arrows.
Centered on the eagle's breast is a shield divided into three sections containing elements that represent the American homeland – air, land, and sea. The top element, a dark blue sky, contains 22 stars representing the original 22 entities that have come together to form the department. The left shield element contains white mountains behind a green plain underneath a light blue sky. The right shield element contains four wave shapes representing the oceans alternating light and dark blue separated by white lines.
The seal was developed with input from senior DHS leadership, employees, and the U.S. Commission on Fine Arts. The Ad Council – which partners with DHS on its Ready.gov campaign – and the consulting company Landor Associates were responsible for graphic design and maintaining heraldic integrity.
Since its inception, the department has had its temporary headquarters in Washington, D.C.'s Nebraska Avenue Complex, a former naval facility. The 38-acre (15 ha) site, across from American University, has 32 buildings comprising 566,000 square feet (52,600 m 2) of administrative space.  In early 2007, the Department submitted a $4.1 billion plan to Congress to consolidate its 60-plus Washington-area offices into a single headquarters complex at the St. Elizabeths Hospital campus in Anacostia, Southeast Washington, D.C. The earliest DHS would begin moving to St. Elizabeths is 2012. 
The move is being championed by District of Columbia officials because of the positive economic impact it will have on historically depressed Anacostia. The move has been criticized by historic preservationists, who claim the revitalization plans will destroy dozens of historic buildings on the campus.  Community activists have criticized the plans because the facility will remain walled off and have little interaction with the surrounding area.  On January 8, 2009, the National Capital Planning Commission approved the Department of Homeland Security's plans to move into the campus of St. Elizabeths Hospital.  In February 2015 the General Services Administration said that the site would open in 2021. 
Disaster preparedness and response
Soon after the formation of Department of Homeland Security, the department worked with the Ad Council to launch the Ready Campaign, a national public service advertising (PSA) campaign to educate and empower Americans to prepare for and respond to emergencies including natural and man-made disasters. With pro bono creative support from the Martin Agency of Richmond, Virginia, the campaign website "Ready.gov" and materials were conceived in March 2002 and launched in February 2003, just before the launch of the Iraq War.    One of the first announcements that garnered widespread public attention to this campaign was one by Tom Ridge in which he stated that in the case of a chemical attack, citizens should use duct tape and plastic sheeting to build a homemade bunker, or "sheltering in place" to protect themselves.   As a result, the sales of duct tape skyrocketed and DHS was criticized for being too alarmist. 
On March 1, 2003, the Federal Emergency Management Agency was absorbed into the DHS, and in fall of 2008, took over coordination of the campaign. The Ready Campaign and its Spanish language version Listo.gov asks individuals to do three things: build an emergency supply kit,  make a family emergency plan  and be informed about the different types of emergencies that can occur and how to respond.  The campaign messages have been promoted through television, radio, print, outdoor and web PSAs,  as well as brochures, toll-free phone lines and the English and Spanish language websites Ready.gov and Listo.gov.
The general campaign aims to reach all Americans, but targeted resources are also available via “Ready Business” for small- to medium-sized business and “Ready Kids” for parents and teachers of children ages 8–12. In 2015, the campaign also launched a series of PSAs to help the whole community,  people with disabilities and others with access and functional needs prepare for emergencies, which included open captioning, a certified deaf interpreter and audio descriptions for viewers who are blind or have low vision. 
National Incident Management System
On March 1, 2004, the National Incident Management System (NIMS) was created. The stated purpose was to provide a consistent incident management approach for federal, state, local, and tribal governments. Under Homeland Security Presidential Directive-5, all federal departments were required to adopt the NIMS and to use it in their individual domestic incident management and emergency prevention, preparedness, response, recovery, and mitigation program and activities.
National Response Framework
In December 2004, the National Response Plan (NRP) was created, in an attempt to align federal coordination structures, capabilities, and resources into a unified, all-discipline, and all-hazards approach to domestic incident management. The NRP was built on the template of the NIMS.
Surge Capacity Force
The Post-Katrina Emergency Management Reform Act directs the DHS Secretary to designate employees from throughout the Department to staff a Surge Capacity Force (SCF). During a declared disaster, the DHS Secretary will determine if SCF support is necessary. The Secretary will then authorize FEMA to task and deploy designated personnel from DHS components and other Federal Executive Agencies to respond to extraordinary disasters. 
The DHS National Cyber Security Division (NCSD) is responsible for the response system, risk management program, and requirements for cyber-security in the U.S. The division is home to US-CERT operations and the National Cyber Alert System.   The DHS Science and Technology Directorate helps government and private end-users transition to new cyber-security capabilities. This directorate also funds the Cyber Security Research and Development Center, which identifies and prioritizes research and development for NCSD.  The center works on the Internet's routing infrastructure (the SPRI program) and Domain Name System (DNSSEC), identity theft and other online criminal activity (ITTC), Internet traffic and networks research (PREDICT datasets and the DETER testbed), Department of Defense and HSARPA exercises (Livewire and Determined Promise), and wireless security in cooperation with Canada. 
On October 30, 2009, DHS opened the National Cybersecurity and Communications Integration Center. The center brings together government organizations responsible for protecting computer networks and networked infrastructure. 
In the United States Federal Budget for 2010, entitled 'A New Era of Responsibility', the DHS was allocated a discretionary budget of $42.7 billion (financial year 2009: $40.1 billion).  The end-of-year DHS Annual Financial Report for financial year 2010 showed a net cost of operations of $56.4 billion (FY 2009, restated: $49.9 billion), out of total budgetary resources of $83.2 billion (FY 2009, restated: $85.2 billion).  The components with the highest net cost were US Coast Guard ($12.1 billion), U.S. Customs and Border Protection ($11.6 billion), and Federal Emergency Management Agency ($10.5 billion).  Revenues of $10.4 billion were generated in the year (FY 2009, restated: $9.8 billion). 
According to the Washington Post, "DHS has given $31 billion in grants since 2003 to state and local governments for homeland security and to improve their ability to find and protect against terrorists, including $3.8 billion in 2010." 
Audit of expenditures
The DHS independent auditor is KPMG, one of the Big Four audit firms.  Due to the level of material weaknesses identified, KPMG was unable to audit the DHS financial statements for FY 2010.  KPMG was unable to express an audit opinion on the FY 2009,  FY 2008,  FY 2007,  FY 2005,  and FY 2003  financial statements. Attempts to access the reports for FY 2006 and FY 2004 within the 'information for citizens' portal met with a 404 error.  The Message from the DHS Chief Financial Officer in the FY 2010 report states 'This Annual Financial Report (AFR) is our principal financial statement of accountability to the President, Congress and the American public. The AFR gives a comprehensive view of the Department's financial activities and demonstrates the Department's stewardship of taxpayer dollars.'  The Message from the DHS Chief Financial Officer concludes 'I am extremely proud of the Department's accomplishments ... we will continue to build upon our successes.'  The Secretary of Homeland Security endorsed this message saying that the DHS is 'continuing to be responsible stewards of taxpayer resources. The scope of our mission is broad, challenging, and vital to the security of the Nation ... Thank you for your partnership and collaboration. Yours very truly, Janet Napolitano.' 
The Department of Homeland Security has received substantial criticism over excessive bureaucracy, waste, fraud, ineffectiveness and lack of transparency. Its information sharing centers have been accused of violating American civil liberties and targeting American citizens as potential threats to national security.
Excess, waste, and ineffectiveness
The Department of Homeland Security has been dogged by persistent criticism over excessive bureaucracy, waste, ineffectiveness and lack of transparency. Congress estimates that the department has wasted roughly $15 billion in failed contracts (as of September 2008).  In 2003, the department came under fire after the media revealed that Laura Callahan, Deputy Chief Information Officer at DHS with responsibilities for sensitive national security databases, had obtained her bachelor, masters, and doctorate computer science degrees through Hamilton University, a diploma mill in a small town in Wyoming.  The department was blamed for up to $2 billion of waste and fraud after audits by the Government Accountability Office revealed widespread misuse of government credit cards by DHS employees, with purchases including beer brewing kits, $70,000 of plastic dog booties that were later deemed unusable, boats purchased at double the retail price (many of which later could not be found), and iPods ostensibly for use in "data storage".    
A 2015 inspection of IT infrastructure found that the department was running over a hundred computer systems whose owners were unknown, including Secret and Top Secret databases, many with out of date security or weak passwords. Basic security reviews were absent, and the department had apparently made deliberate attempts to delay publication of information about the flaws. 
Data mining (ADVISE)
The Associated Press reported on September 5, 2007, that DHS had scrapped an anti-terrorism data mining tool called ADVISE (Analysis, Dissemination, Visualization, Insight and Semantic Enhancement) after the agency's internal Inspector General found that pilot testing of the system had been performed using data on real people without required privacy safeguards in place.   The system, in development at Lawrence Livermore and Pacific Northwest National Laboratory since 2003, has cost the agency $42 million to date. Controversy over the program is not new; in March 2007, the Government Accountability Office stated that "the ADVISE tool could misidentify or erroneously associate an individual with undesirable activity such as fraud, crime or terrorism." Homeland Security's Inspector General later said that ADVISE was poorly planned, time-consuming for analysts to use, and lacked adequate justifications. 
Fusion centers are terrorism prevention and response centers, many of which were created under a joint project between the Department of Homeland Security and the US Department of Justice's Office of Justice Programs between 2003 and 2007. The fusion centers gather information not only from government sources, but also from their partners in the private sector.  
They are designed to promote information sharing at the federal level between agencies such as the Central Intelligence Agency (CIA), Federal Bureau of Investigation (FBI), Department of Justice, US Military and state and local level government. As of July 2009, the Department of Homeland Security recognized at least seventy-two fusion centers.  Fusion centers may also be affiliated with an Emergency Operations Center that responds in the event of a disaster.
There are a number of documented criticisms of fusion centers, including relative ineffectiveness at counterterrorism activities, the potential to be used for secondary purposes unrelated to counterterrorism, and their links to violations of civil liberties of American citizens and others. 
David Rittgers of the Cato Institute has noted:
a long line of fusion center and DHS reports labeling broad swaths of the public as a threat to national security. The North Texas Fusion System labeled Muslim lobbyists as a potential threat; a DHS analyst in Wisconsin thought both pro- and anti-abortion activists were worrisome; a Pennsylvania homeland security contractor watched environmental activists, Tea Party groups, and a Second Amendment rally; the Maryland State Police put anti-death penalty and anti-war activists in a federal terrorism database; a fusion center in Missouri thought that all third-party voters and Ron Paul supporters were a threat.... 
The Missouri Information Analysis Center (MIAC) made news in 2009 for targeting supporters of third party candidates (such as Ron Paul), pro-life activists, and conspiracy theorists as potential militia members.  Anti-war activists and Islamic lobby groups were targeted in Texas, drawing criticism from the American Civil Liberties Union. 
The Privacy Office has identified a number of risks to privacy presented by the fusion center program:
- Justification for fusion centers
- Ambiguous Lines of Authority, Rules, and Oversight
- Participation of the Military and the Private Sector
- Data Mining
- Excessive Secrecy
- Inaccurate or Incomplete Information
- Mission Creep
2009 Virginia terrorism threat assessment
In early April 2009, the Virginia Fusion Center came under criticism for publishing a terrorism threat assessment which stated that certain universities are potential hubs for terror related activity.  The report targeted historically black colleges and identified hacktivism as a form of terrorism. 
In 2006, MSNBC reported that Grant Goodman, "an 81-year-old retired University of Kansas history professor, received a letter from his friend in the Philippines that had been opened and resealed with a strip of dark green tape bearing the words "by Border Protection " and carrying the official Homeland Security seal."  The letter was sent by a devout Catholic Filipino woman with no history of supporting Islamic terrorism.  A spokesman for U.S. Customs and Border Protection "acknowledged that the agency can, will and does open mail coming to U.S. citizens that originates from a foreign country whenever it's deemed necessary":
"All mail originating outside the United States Customs territory that is to be delivered inside the U.S. Customs territory is subject to Customs examination," says the CBP Web site. That includes personal correspondence. "All mail means 'all mail,'" said John Mohan, a CBP spokesman, emphasizing the point. 
The Department declined to outline what criteria are used to determine when a piece of personal correspondence should be opened or to say how often or in what volume Customs might be opening mail. 
Goodman's story provoked outrage in the blogosphere,  as well as in the more established media. Reacting to the incident, Mother Jones remarked that "[u]nlike other prying government agencies, Homeland Security wants you to know it is watching you."  CNN observed that "[o]n the heels of the NSA wiretapping controversy, Goodman's letter raises more concern over the balance between privacy and security." 
In July 2006, the Office of Personnel Management conducted a survey of federal employees in all 36 federal agencies on job satisfaction and how they felt their respective agency was headed. DHS was last or near to last in every category including;
- 33rd on the talent management index
- 35th on the leadership and knowledge management index
- 36th on the job satisfaction index
- 36th on the results-oriented performance culture index
The low scores were attributed to major concerns about basic supervision, management and leadership within the agency. Examples from the survey reveal most concerns are about promotion and pay increase based on merit, dealing with poor performance, rewarding creativity and innovation, leadership generating high levels of motivation in the workforce, recognition for doing a good job, lack of satisfaction with various component policies and procedures and lack of information about what is going on with the organization.  
DHS is the only large federal agency to score below 50% in overall survey rankings. It was last of large federal agencies in 2014 with 44.0% and fell even lower in 2015 at 43.1%, again last place. 
Freedom of Information Act processing performance
In the latest Center for Effective Government analysis of 15 federal agencies which receive the most Freedom of Information Act FOIA requests, published in 2015 (using 2012 and 2013 data, the most recent years available), the Department of Homeland Security earned a D by scoring 69 out of a possible 100 points, i.e. did not earn a satisfactory overall grade. It also had not updated its FOIA policies since the 2007 FOIA amendments.
