Surveillance Detection Unit
A Surveillance Detection Unit (SDU) is a specialized organization functioning under the umbrella of the United States Government primarily tasked with conducting surveillance to identify and counter threats. These units often operate under the purview of the U.S. Department of State, particularly in safeguarding embassies and consulates across the globe.
In 2000, the U.S. Congress publicly discussed the existence of a "worldwide surveillance detection program" emphasizing quasi-covert operations and information gathering. This initiative led to the establishment of SDUs in at least 22 U.S. embassies and consulates globally. These units work under the authority of the Regional Security Officer (RSO), who is a special agent of the Diplomatic Security Service.
The SDUs collect, analyze, and store surveillance data in a system known as the Security Incident Management Analysis System. The primary goal is to detect hostile surveillance directed at U.S. diplomatic missions. This process involves gathering information that could preempt potential terrorist attacks or other security threats.
In Norway, the existence of such units sparked significant public debate. The Norwegian broadcaster TV 2 revealed the presence of SDUs in 2010, which led to a controversy over the legality and transparency of these operations. Notable Norwegian institutions such as the Norwegian Police Security Service and the National Criminal Investigation Service were reportedly involved in the surveillance activities near the U.S. embassy in Oslo.
The RSO oversees the operations of the SDU, ensuring that surveillance activities align with diplomatic security protocols. The RSO, often referred to as the "security attaché," is responsible for the safety of the diplomatic mission's personnel and premises.
The Security Incident Management Analysis System is a sophisticated database where collected surveillance data is stored. This system allows for the efficient analysis and management of security incidents, aiding in the prevention of potential threats.
The Norwegian Police Security Service (PST) is Norway's police security agency, tasked with national security and intelligence operations. The PST collaborated with the U.S. embassy's SDUs to monitor and mitigate threats.
The Diplomatic Security Service (DSS) is the security and law enforcement arm of the U.S. Department of State. The DSS manages the RSOs and supports the SDUs in their mission to protect U.S. diplomatic interests globally.
