of State facilities. Beginning in the late 1960s, several ambassadors and Department officials were kidnapped or assassinated. These actions highlighted the possible exploitation of U.S. diplomats for political purposes. To meet this new threat, SY increased its protective capabilities. The rages of terrorism continued, creating a new and increasingly dangerous threat to U.S. citizens and missions abroad, as well as to distinguished visitors to the United States. SY responded to the emerging threat by hiring over a hundred new agents and purchasing vehicles, radios, and other support equipment. SY published handbooks on terrorism and provided advice for overseas personnel on traveling safely to and from work and how to make their homes safer. SY began to survey U.S. embassies for vulnerability to attack. Security officers received more intensive training and learned new skills, like defensive driving. In 1961, according to at least one source, Otto Otepka, then the Director of SY, brought to the attention of the United States Senate Internal Security Subcommittee deficiencies in the State Department clearance process. The allegations were traced all the way up to then-United States Secretary of State Dean Rusk. Despite multiple awards, appeals from multiple U.S. Senators, and despite having maintained his integrity by not backing down, Secretary Rusk removed Otepka from his position and ultimately fired him. Today, the Diplomatic Security Counterintelligence Directorate conducts a robust counterintelligence program designed to deter, detect, and neutralize the efforts of foreign intelligence services targeting Department of State personnel, facilities, and diplomatic missions worldwide. The counterintelligence division conducts aggressive counterintelligence inquires and counterespionage investigations with other U.S. Government agencies. All counterespionage investigations are conducted in close coordination with the FBI in accordance with their statutory mandate to prosecute instances or allegations of suspected espionage. The division conducts numerous counterintelligence and security awareness training programs for all U.S. Government personnel requesting or having access to sensitive Department of State facilities and information. All training programs enhance the understanding of both foreign intelligence and espionage threats and countermeasures, and educate employees on the foreign intelligence environment. In addition, the office relies on a cadre of security engineers to deter, detect, and neutralize attempts by foreign intelligence services to technically penetrate Department of State office buildings and residences. These efforts range from detecting a simple listening device in the wall to countering the most sophisticated electronic eavesdropping devices and systems.
