Intelligence agency in the context of "Security agency"

The Central Intelligence Agency (CIA /ˌsiː.aɪˈeɪ/) is a civilian foreign intelligence service of the federal government of the United States tasked with advancing national security through collecting and analyzing intelligence from around the world and conducting covert operations. The agency is headquartered in the George Bush Center for Intelligence in Langley, Virginia, and is sometimes metonymously called "Langley". A major member of the United States Intelligence Community (IC), the CIA has reported to the director of national intelligence since 2004, and is focused on providing intelligence for the president and the Cabinet, though it also provides intelligence for a variety of other entities including the US Military and foreign allies.

The CIA is headed by a director and is divided into various directorates, including a Directorate of Analysis and Directorate of Operations. Unlike the Federal Bureau of Investigation (FBI), the CIA has no law enforcement function and focuses on intelligence gathering overseas, with only limited domestic intelligence collection. The CIA is responsible for coordinating all human intelligence (HUMINT) activities in the IC. It has been instrumental in establishing intelligence services in many countries, and has provided support to many foreign organizations. The CIA exerts foreign political influence through its paramilitary operations units, including its Special Activities Center. It has also provided support to several foreign political groups and governments, including planning, coordinating, training and carrying out torture, and technical support. It was involved in many regime changes and carrying out planned assassinations of foreign leaders and terrorist attacks against civilians.

The United States Intelligence Community (IC) is a group of separate U.S. federal government intelligence agencies and subordinate organizations that work to conduct intelligence activities which support the foreign policy and national security interests of the United States. Member organizations of the IC include intelligence agencies, military intelligence, and civilian intelligence and analysis offices within federal executive departments.

The IC is overseen by the Office of the Director of National Intelligence (ODNI), which is headed by the director of national intelligence (DNI) who reports directly to the president of the United States. The IC was established by Executive Order 12333 ("United States Intelligence Activities"), signed on December 4, 1981, by President Ronald Reagan. The statutory definition of the IC, including its roster of agencies, was codified as the Intelligence Organization Act of 1992 (Pub. L. 102–496, H.R. 5095, 106 Stat. 3188).

The Defense Intelligence Agency (DIA) is an intelligence agency and combat support agency of the United States Department of Defense (DoD) specializing in military intelligence.

A component of the Department of Defense and the Intelligence Community (IC), DIA informs national civilian and defense policymakers about the military intentions and capabilities of foreign governments and non-state actors. It also provides intelligence assistance, integration and coordination across uniformed military service intelligence components, which remain structurally separate from DIA. The agency's role encompasses the collection and analysis of military-related foreign political, economic, industrial, geographic, and medical and health intelligence. DIA produces approximately one-quarter of all intelligence content that goes into the President's Daily Brief.

The National Security Agency (NSA) is an intelligence agency of the United States Department of Defense, under the authority of the director of national intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for global intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The NSA has roughly 32,000 employees.

Originating as a unit to decipher coded communications in World War II, it was officially formed as the NSA by President Harry S. Truman in 1952. Between then and the end of the Cold War, it became the largest of the U.S. intelligence organizations in terms of personnel and budget. Still, information available as of 2013 indicates that the Central Intelligence Agency (CIA) pulled ahead in this regard, with a budget of $14.7 billion. The NSA currently conducts worldwide mass data collection and has been known to physically bug electronic systems as one method to this end. The NSA is also alleged to have been behind such attack software as Stuxnet, which severely damaged Iran's nuclear program. The NSA, alongside the CIA, maintains a physical presence in many countries across the globe; the CIA/NSA joint Special Collection Service (a highly classified intelligence team) inserts eavesdropping devices in high-value targets (such as presidential palaces or embassies). SCS collection tactics allegedly encompass "close surveillance, burglary, wiretapping, [and] breaking".

The Federal Bureau of Investigation (FBI) is the primary federal law enforcement agency in the United States and also the American domestic intelligence and security service. An agency of the United States Department of Justice, the FBI is a member of the U.S. Intelligence Community and reports to both the attorney general and the director of national intelligence. A leading American counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. The FBI maintains a list of its top 10 most wanted fugitives.

Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.

The right to privacy is an element of various legal traditions that intends to restrain governmental and private actions that threaten the privacy of individuals. Over 185 national constitutions mention the right to privacy. Since the global surveillance disclosures of 2013, the right to privacy has been a subject of international debate. Government agencies, such as the NSA, FBI, CIA, R&AW, and GCHQ, have engaged in mass, global surveillance. Some current debates around the right to privacy include whether privacy can co-exist with the current capabilities of intelligence agencies to access and analyze many details of an individual's life; whether or not the right to privacy is forfeited as part of the social contract to bolster defense against supposed terrorist threats; and whether threats of terrorism are a valid excuse to spy on the general population. Private sector actors can also threaten the right to privacy – particularly technology companies, such as Amazon, Apple, Meta, Google, Microsoft, and Yahoo that use and collect personal data.

The militarization of police (paramilitarization of police in some media) is the use of military equipment and tactics by law enforcement officers. This includes the use of armored personnel carriers (APCs), assault rifles, submachine guns, flashbang grenades, sniper rifles, and SWAT (special weapons and tactics) teams. The militarization of law enforcement is also associated with intelligence agency–style information gathering aimed at the public and political activists and with a more aggressive style of law enforcement. Criminal justice professor Peter Kraska has defined militarization of police as "the process whereby civilian police increasingly draw from, and pattern themselves around, the tenets of militarism and the military model".

Observers have noted the militarizing of the policing of protests. Since the 1970s, riot police have fired at protesters using guns with rubber bullets or plastic bullets. Tear gas, which was developed by the United States Army for riot control in 1919, is still widely used against protesters. The use of tear gas in warfare is prohibited by various international treaties that most states have signed; however, its law enforcement or military use for domestic or non-combat situations is permitted.

Secret police (or political police) are police, intelligence or security agencies that engage in covert operations against a government's political, ideological or social opponents and dissidents. Secret police organizations are characteristic of authoritarian and totalitarian regimes. They protect the political power of a dictator or regime and often operate outside the law to repress dissidents and weaken political opposition, frequently using violence. They may enjoy legal sanction to hold and charge suspects without ever identifying their organization.

The People's Commissariat for Internal Affairs (Russian: Народный комиссариат внутренних дел, romanized: Narodnyy komissariat vnutrennikh del, IPA: [nɐˈrodnɨj kəmʲɪsərʲɪˈat ˈvnutrʲɪnʲɪɣ dʲel]), abbreviated as NKVD (Russian: НКВД; listen), was the interior ministry and secret police of the Soviet Union from 1934 to 1946. The agency was formed to succeed the Joint State Political Directorate (OGPU) secret police organization, and thus had a monopoly on intelligence and state security functions. The NKVD is known for carrying out political repression and the Great Purge under Joseph Stalin, as well as counterintelligence and other operations on the Eastern Front of World War II. The head of the NKVD was Genrikh Yagoda from 1934 to 1936, Nikolai Yezhov from 1936 to 1938, Lavrentiy Beria from 1938 to 1946, and Sergei Kruglov in 1946.

First established in 1917 as the NKVD of the Russian SFSR, the ministry was tasked with regular police work and overseeing the country's prisons and labor camps. It was disbanded in 1930, and its functions dispersed among other agencies before being reinstated as a commissariat of the Soviet Union in 1934. During the Great Purge in 1936–1938, on Stalin's orders, the NKVD conducted mass arrests, imprisonment, torture, and executions of hundreds of thousands of Soviet citizens. The agency sent millions to the Gulag system of forced labor camps and, during World War II, carried out the mass deportations of hundreds of thousands of Poles, Balts, and Romanians, and millions of ethnic minorities from the Caucasus, to remote areas of the country, resulting in millions of deaths. Hundreds of thousands of NKVD personnel served in Internal Troops divisions in defensive battles alongside the Red Army, as well as in "blocking formations," preventing retreat. The agency was responsible for foreign assassinations, including that of Leon Trotsky.
