'This U.S. Army film discusses security awareness and responsibilities in relation to overseas travel.'

Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Counterintelligence is an activity aimed at protecting an agency's intelligence program against an opposition's intelligence service. It likewise refers to information gathered and activities conducted to counter espionage, sabotage, assassinations or other intelligence activities conducted for or on behalf of foreign powers, organizations or persons, international terrorist activities, sometimes including personnel, physical, document, or communications security programs...

Many governments organize counterintelligence agencies separately and distinct from their intelligence collection services. In most countries the counterintelligence mission is spread over multiple organizations, though one usually predominates. There is usually a domestic counterintelligence service, usually part of a larger law enforcement organization such as the Federal Bureau of Investigation in the United States.

The United Kingdom has the separate Security Service, also known as MI5, which does not have direct police powers but works closely with law enforcement especially Special Branch that can carry out arrests, do searches with a warrant, etc.

The Russian Federation's major domestic security organization is the FSB, which principally came from the Second Chief Directorate and Third Chief Directorate of the USSR's KGB.

Canada separates the functions of general defensive counterintelligence (contre-ingérence), security intelligence (the intelligence preparation necessary to conduct offensive counterintelligence), law enforcement intelligence, and offensive counterintelligence.

Military organizations have their own counterintelligence forces, capable of conducting protective operations both at home and when deployed abroad. Depending on the country, there can be various mixtures of civilian and military in foreign operations. For example, while offensive counterintelligence is a mission of the US CIA's National Clandestine Service, defensive counterintelligence is a mission of the U.S. Diplomatic Security Service (DSS), Department of State, who work on protective security for personnel and information processed abroad at US Embassies and Consulates.

The term counter-espionage is really specific to countering HUMINT, but, since virtually all offensive counterintelligence involves exploiting human sources, the term "offensive counterintelligence" is used here to avoid some ambiguous phrasing.

Other countries also deal with the proper organization of defenses against Foreign Intelligence Services (FIS), often with separate services with no common authority below the head of government...

Frank Wisner, a well-known CIA operations executive said of the autobiography of Director of Central Intelligence Allen W. Dulles, that Dulles "disposes of the popular misconception that counterintelligence is essentially a negative and responsive activity, that it moves only or chiefly in reaction to situations thrust upon it and in counter to initiatives mounted by the opposition." Rather, he sees that can be most effective, both in information gathering and protecting friendly intelligence services, when it creatively but vigorously attacks the "structure and personnel of hostile intelligence services." Today's counterintelligence missions have broadened from the time when the threat was restricted to the foreign intelligence services (FIS) under the control of nation-states. Threats have broadened to include threats from non-national or trans-national groups, including internal insurgents, organized crime, and transnational based groups (often called "terrorists", but that is limiting). Still, the FIS term remains the usual way of referring to the threat against which counterintelligence protects...
