Frank Wisner Frank Gardiner Wisner (June 23, 1909 – October 29, 1965) was one of the founding officers of the Central Intelligence Agency (CIA) and played a major role in CIA operations throughout the 1950s. Wisner began his intelligence career in the Off ...
, 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. In modern practice, several missions are associated with counterintelligence from the national to the field level. * Defensive analysis is the practice of looking for vulnerabilities in one's own organization, and, with due regard for risk versus benefit, closing the discovered holes. * Offensive counterespionage is the set of techniques that at least neutralizes discovered FIS personnel and arrests them or, in the case of diplomats, expels them by declaring them

Beyond that minimum, it exploits FIS personnel to gain intelligence for one's own side, or actively manipulates the FIS personnel to damage the hostile FIS organization. * Counterintelligence force protection source operations (CFSO) are human source operations, conducted abroad that are intended to fill the existing gap in national-level coverage in protecting a field station or force from terrorism and espionage.

(OPSEC) The disciplines involved in "positive security," measures by which one's own society collects information on its actual or potential security, complement security. For example, when communications intelligence identifies a particular radio transmitter as one used only by a particular country, detecting that transmitter inside one's own country suggests the presence of a spy that counterintelligence should target. In particular, counterintelligence has a significant relationship with the collection discipline of

authority. Governments try to protect three things: *Their personnel *Their installations *Their operations In many governments, the responsibility for protecting these things is split. Historically, CIA assigned responsibility for protecting its personnel and operations to its Office of Security, while it assigned the security of operations to multiple groups within the Directorate of Operations: the counterintelligence staff and the area (or functional) unit, such as Soviet Russia Division. At one point, the counterintelligence unit operated quite autonomously, under the direction of

was in the Counterintelligence Branch of Europe Division, where he was responsible for directing the analysis of Soviet intelligence operations. US military services have had a similar and even more complex split. This kind of division clearly requires close coordination, and this in fact occurs on a daily basis. The interdependence of the US counterintelligence community is also manifest in its relationships with liaison services. The counterintelligence community cannot cut off these relationships because of concern about security, but experience has shown that it must calculate the risks involved. On the other side of the CI coin, counterespionage has one purpose that transcends all others in importance: penetration. The emphasis which the KGB places on penetration is evident in the cases already discussed from the defensive or security viewpoint. The best security system in the world cannot provide an adequate defense against it because the technique involves people. The only way to be sure that an enemy has been contained is to know his plans in advance and in detail.
Moreover, only a high-level penetration of the opposition can tell you whether your own service is penetrated. A high-level defector can also do this, but the adversary knows that he defected and within limits can take remedial action. Conducting CE without the aid of penetrations is like fighting in the dark. Conducting CE with penetrations can be like
