Espionage is a part of intelligence activity, which is also concerned with analysis of diplomatic reports, newspapers, periodicals, technical publications, commercial statistics, and radio and television broadcasts. In the last fifty years espionage activity has been greatly supplemented by technological advances, especially in the areas of radio signal interception and high-altitude photography. Surveillance with high-technology equipment on the ground or from high-altitude planes and satellites has become an important espionage technique (see Cuban Missile Crisis). The development of the Internet has created opportunities for espionage through hacking into foreign government and private computers, through electronic surveillance of Internet and network traffic, and through the use of trojan horses, key loggers, and such computer programs. Code making and code breaking (see cryptography) have become computerized and very effective. The threat of foreign espionage is used as an excuse for internal suppression and the suspension of civil rights in many countries. Espionage is a very important part of guerrilla warfare and counterinsurgency. The defensive side of intelligence activity, i.e., preventing another nation from gaining such information, is known as counterespionage. Under international law, intelligence activities are not illegal; however, every nation has laws against espionage conducted against it.
The importance of espionage in military affairs has been recognized since the beginning of recorded history. The Egyptians had a well-developed secret service, and spying and subversion are mentioned in the Iliad and in the Bible. The ancient Chinese treatise (c.500 B.C.) on the art of war (see Sun Tzu) devotes much attention to deception and intelligence gathering, arguing that all war is based on deception. In the Middle Ages, political espionage became important. Joan of Arc was betrayed by Bishop Pierre Cauchon of Beauvais, a spy in the pay of the English, and Sir Francis Walsingham developed an efficient political spy system for Elizabeth I. With the growth of the modern national state, systematized espionage became a fundamental part of government in most countries. Joseph Fouché is credited with developing the first modern political espionage system, and Frederick II of Prussia is regarded as the founder of modern military espionage. During the American Revolution, Nathan Hale and Benedict Arnold achieved fame as spies, and there was considerable use of spies on both sides during the U.S. Civil War.In the Twentieth Century
By World War I, all the great powers except the United States had elaborate civilian espionage systems and all national military establishments had intelligence units. To protect the country against foreign agents, the U.S. Congress passed the Espionage Statute of 1917. Mata Hari, who obtained information for Germany by seducing French officials, was the most noted espionage agent of World War I. Germany and Japan established elaborate espionage nets in the years preceding World War II. In 1942 the Office of Strategic Services was founded by Gen. William J. Donovan. However, the British system was the keystone of Allied intelligence.
Since World War II, espionage activity has enlarged considerably, much of it growing out of the cold war between the United States and the former USSR. Russia and the Soviet Union have had a long tradition of espionage ranging from the Czar's Okhrana to the Committee for State Security (the KGB), which also acted as a secret police force. In the United States the 1947 National Security Act created the Central Intelligence Agency (CIA) to coordinate intelligence and the National Security Agency for research into codes and electronic communication. In addition to these, the United States has 13 other intelligence gathering agencies; most of the U.S. expenditures for intelligence gathering are budgeted to various Defense Dept. agencies and their programs. Under the intelligence reorganization of 2004, the director of national intelligence is responsible for overseeing and coordinating the activities and budgets of the U.S. intelligence agencies.
Famous cold war espionage cases include Alger Hiss and Whittaker Chambers and the Rosenberg Case. In 1952 the Communist Chinese captured two CIA agents, and in 1960 Francis Gary Powers, flying a U-2 reconnaissance mission over the Soviet Union for the CIA, was shot down and captured. During the cold war, many Soviet intelligence officials defected to the West, including Gen. Walter Krivitsky, Victor Kravchenko, Vladimir Petrov, Peter Deriabin Pawel Monat, and Oleg Penkovsky, of the GRU (Soviet military intelligence). Among Western officials who defected to the Soviet Union are Guy F. Burgess and Donald D. Maclean of Great Britain in 1951, Otto John of West Germany in 1954, William H. Martin and Bernon F. Mitchell, U.S. cryptographers, in 1960, and Harold (Kim) Philby of Great Britain in 1962. U.S. acknowledgment of its U-2 flights and the exchange of Francis Gary Powers for Rudolf Abel in 1962 implied the legitimacy of some espionage as an arm of foreign policy.
China has a very cost-effective intelligence program that is especially effective in monitoring neighboring countries. Smaller countries can also mount effective and focused espionage efforts. The Vietnamese Communists, for example, had consistently superior intelligence during the Vietnam War. Israel probably has the best espionage establishment in the world. Some of the Muslim countries, especially Libya, Iran, and Syria, have highly developed operations as well. Iran's Savak was particularly feared by Iranian dissidents before the Iranian Revolution.
See A. Ind, A Short History of Espionage (1963); R. W. Rowan and R. G. Deindorfer, Secret Service: Thirty-Three Centuries of Espionage (rev. ed. 1967); R. Friedman, Advanced Technology Warfare (1985); G. Treverton, Covert Action (1989); J. Keegan, Intelligence in War (2003).
Espionage or spying involves an individual obtaining information that is considered secret or confidential without the permission of the holder of the information. Espionage is inherently clandestine, as the legitimate holder of the information may change plans or take other countermeasures once it is known that the information is in unauthorized hands. See clandestine HUMINT for the basic concepts of such information collection, and subordinate articles such as clandestine HUMINT operational techniques and clandestine HUMINT asset recruiting for discussions of the "tradecraft" used to collect this information.
The Cold War involved intense espionage activity between the United States of America and its allies and the Soviet Union and the People's Republic of China and their allies, particularly related to nuclear weapons secrets. Recently, espionage agencies have targeted the illegal drug trade and those considered to be terrorists.
Different intelligence services value certain intelligence collection techniques over others. The former Soviet Union, for example, preferred human sources over research in open sources, while the United States has tended to emphasize technological methods such as SIGINT and IMINT. Both Soviet political (KGB) and military intelligence (GRU) officers were judged by the number of agents they recruited.
The US defines espionage towards itself as "The act of obtaining, delivering, transmitting, communicating, or receiving information about the national defense with an intent, or reason to believe, that the information may be used to the injury of the United States or to the advantage of any foreign nation. Espionage is a violation of 18 United States Code 792-798 and Article 106, Uniform Code of Military Justice." The United States, like most nations, conducts espionage against other nations, under the control of the National Clandestine Service. Britain's espionage activities are controlled by the Secret Intelligence Service.
Espionage is usually part of an institutional effort (i.e., governmental or corporate espionage), and the term is most readily associated with state spying on potential or actual enemies, primarily for military purposes, but this has been extended to spying involving corporations, known specifically as industrial espionage. Many nations routinely spy on both their enemies and allies, although they maintain a policy of not making comment on this. In addition to utilizing agencies within a government many also employ private companies to collect information on their behalf such as SCG International Risk and others. Black's Law Dictionary (1990) defines espionage as: "...gathering, transmitting, or losing...information related to the national defense."
While news media may speak of "spy satellites" and the like, espionage is not a synonym for all types of intelligence functions. It is a specific form of human source intelligence (HUMINT). Codebreaking (cryptanalysis or COMINT), aircraft or satellite photography (IMINT) and research in open publications (OSINT) are all intelligence gathering disciplines, but none of them are espionage. Not all HUMINT activities, such as interviewing prisoners, reports from military reconnaissance patrols and from diplomats, etc., are espionage.
A spy is a person employed to obtain such secrets. Within the US intelligence community, asset is a more common usage. A case officer, who may have diplomatic status (i.e., official cover or non-official cover) supports and directs the human collector. Cutouts are couriers who do not know the agent or case officer, but transfer messages. A safe house is a refuge for spies.
In larger networks, the organization can be complex, with many methods to avoid detection, including clandestine cell systems. Often the players have never met and are sometimes unaware that they are participating. This is often referred to as "the Tyson Effect," where important players are unaware of their own participation. See Clandestine HUMINT for details of the actual operations and people of espionage systems.
Case officers are stationed in foreign countries to recruit and supervise intelligence agents, who in turn spy on targets in their countries where they are assigned. A spy may or may not be an actual citizen of a target country. While the more common practice is to recruit a person already trusted with access to sensitive information, there are cases where a person may attempt to infiltrate a target organization, with a well-prepared synthetic identity for them, called a legend in tradecraft.
These agents can be moles (who are recruited before they get access to secrets), defectors (who are recruited after they get access to secrets and leave their country) or defectors in place (who get access but do not leave).
Many organizations, both national and non-national, conduct espionage operations. It should not be assumed that espionage is always directed at the most secret operations of a target country; national and terrorist organizations and other groups needed to get agents into target countries to learn security routines around their targets. They also needed to arrange secure ways of transferring money.
Communications both are necessary to espionage and clandestine operations, and also a great vulnerability when the adversary has sophisticated SIGINT detection and interception capability.
See espionage organizations for national and non-national groups that conduct clandestine human operations, for any of a number of reasons: assessment of national capabilities at the strategic level, warning of the movements of security and military organizations; financial systems; protective measures around targets. Be aware that certain organizations who have an association with espionage, such as the US FBI, UK Security Service, and Canadian Security Intelligence Service do not perform espionage, but, with these three examples, all monitor and defend against it, the CSIS principally at an analytical levels. In the US and UK, respectively, the National Clandestine Service, part of the Central Intelligence Agency, performs espionage, while the Secret Intelligence Service does so for Great Britain. Canada does not appear to run espionage, although it collects SIGINT. The Russian SVR performs espionage while the FSB defends against it.
An early example of espionage literature is Kim by the English novelist Rudyard Kipling, with a description of the training of an intelligence agent in the "Great Game" between the UK and Russia in 19th century Central Asia.
During the many 20th century spy scandals, a large amount of information became publicly known about national spy agencies and dozens of real-life secret agents. These sensational stories piqued public interest in a profession largely off-limits to human interest news reporting, a natural consequence of the secrecy inherent to their work. To fill in the blanks, the popular conception of the secret agent has been formed largely by 20th and 21st century literature and cinema. While it is obvious from reading news accounts that many real spies, such as Valerie Plame, are attractive and sociable, the fictional secret agent is often a loner, sometimes amoral—an existential hero operating outside the everyday constraints of society. Loner spy personalities may have been a stereotype of convenience for authors who already knew how to write loner private investigator characters that sold well from the 1920s to the present.
While fictional secret agents, such as Johnny Fedora, were popular during the 1950s and 60s, James Bond, the protagonist of Ian Fleming's novels, who went on to spawn an extremely successful film franchise, is the most famous fictional secret agent of all: he uses the best toys and excels at fighting and seduction, completely ignoring the more tedious side of espionage. In direct contrast to this, John le Carré's character George Smiley is often considered the "anti-Bond" and one of the more realistic fictional spies: he is a finite and imperfect man, initially defeated by enemies within the Secret Service, who eventually prevails by patience, intelligence, and compassion. Another is the boy spy Alex Rider, created by Anthony Horowitz; Rider is said to be useful due to his youth. Other popular spies are the characters Johnny Fedora by Desmond Cory; Quiller by Adam Hall; Nikita, played by Peta Wilson, and Michael Samuelle, played by Roy Dupuis, in the TV series La Femme Nikita (1997–2001), Jack Ryan in numerous Tom Clancy novels, and Sydney Bristow, played by Jennifer Garner, in the TV series Alias (2001–2006). The British TV series Spooks is another example of spy fiction. Charlie's Angels has some spying aspects and the popular cartoon series Totally Spies! revolves around three girls named Clover, Sam and Alex who are spies working for a spy agency called WOOHP which stands for World Organization of Human Protection.
Spy fiction has also become prevalent in video gaming, where the "wetwork" aspect of espionage is highlighted. Game situations typically involve agents sent into enemy territory for purposes of subversion. These depictions are more action-oriented than would be typical in most cases of espionage, and they tend to focus on infiltration rather than information-gathering. Some examples are GoldenEye 007, Perfect Dark, Thief, Metal Gear and Splinter Cell. Recent incarnations have attempted to introduce more psychological aspects of infiltration, such as social camouflage and moral decision making, into gameplay.
