context_page_description: The Bureau of Diplomatic Security, more commonly known as Diplomatic Security, or DS, is the security and law enforcement arm of the United States Department of State. DS is a world leader in international investigations, threat analysis, cyber security, counterterrorism, security technology, and protection of people, property, and information. DS's mission is to provide a safe and secure environment for officials to carry out U.S. foreign policy.
context_section_description: Special Agents of the U.S. Diplomatic Security Service - DSS are sworn Federal law enforcement agents who are responsible for the security of Foreign Service personnel, property and sensitive information throughout the world. Although the Diplomatic Security Service (DSS) is an organization within the Bureau of Diplomatic Security, it is the primary conduit utilized by the Bureau of Diplomatic Security for the majority of all law enforcement and security matters.  The DSS is the federal law enforcement branch of the Bureau of Diplomatic Security.  DSS Special Agents are responsible for the protection of the Secretary of State, certain foreign dignitaries during their visits to the U.S., and others as designated by the Secretary of State. Major activities include protective services, management of security programs for Foreign Service posts, criminal investigations, and background investigations, in addition to administrative, training, and liaison functions.
  Security Engineering Officers (SEO) are responsible for managing the Department's technical and information security programs, projects, and resources throughout the world. SEOs protect personnel, facilities, and sensitive information against espionage, terrorism, and crime. These highly skilled engineers develop, maintain, and install electrical and mechanical systems such as access and perimeter controls, closed-circuit television, alarms, locks, and x-ray and bomb detection equipment. Engineers plan and conduct technical surveillance inspections to detect and nullify clandestine intrusions. They test new technical equipment and develop new techniques, strategies, and procedures for finding hidden intelligence-gathering devices. SEOs continually are challenged to identify security risks, analyze those risks, and develop systems to ensure the integrity of Department of State computers and worldwide network information systems. U.S. Navy Seabees and a cadre of specially trained Security Technical Specialists (STS) assist SEOs with the maintenance and repair of our security systems.  Domestically SEO's manage, plan, and provide engineering support to worldwide technical security programs and to the Secretary of State and visiting dignitaries.  Overseas SEO's manage Engineering Service Centers (ESC) and Engineering Service Offices (ESO), which provide technical security to one or multiple posts under the management of Regional Security Officers (RSO).
  Security Technical Specialists (STS) are support personnel within the Bureau of Diplomatic Security who assist in worldwide technical security programs. These programs provide protection for Department of State facilities and personnel from technical espionage, acts of terrorism, and crime. In this protection effort, sophisticated electronic and electromechanical security systems are used throughout the world, which include: intrusion detection systems (IDS), closed-circuit television (CCTV) systems, vehicular and pedestrian access control systems, metal detectors, and explosive detection systems.  STS's support technical security support domestically and at ESC's and ESO's worldwide.
  Diplomatic Couriers protect information by ensuring the secure movement of classified U.S. Government material across international borders to over 180 Foreign Service missions. Diplomatic pouches can contain thousands of pounds of equipment and construction materials, as well as classified documents bound for sensitive posts. Additionally, Diplomatic courier control officers escort sensitive, but unclassified, crated materials within the United States and across international boundaries. These materials receive the same secure shipment as diplomatic pouches but, unlike diplomatic pouches, are declared to customs on entry into a country. The Diplomatic Courier Service securely delivered over 9.5 million pounds of classified material and 1 million pounds of controlled material last year. The Diplomatic Courier Service is constantly evolving to meet the increasingly restrictive guidelines imposed by various countries.
