Central Scientiﬁc and Technological Information Agency (CSTIA)
North Korea is one of the few countries where censorship can be judged by what is seen online, rather than what is missing. The country is not linked to the Internet proper and the authorities keep most of the population isolated from the rest of the world and even from the national intranet. The intranet was developed by the Central Scientiﬁc and Technological Information Agency (CSTIA) and is highly restricted and closely controlled by the domestic intelligence agencies. Its goal is not to keep the population informed but merely to broadcast the official ideology and strengthen the technical skills of those who work for the fatherland. To enforce this wall of silence, special units such as Group 109 and Department 27 are dedicated to tracking down digital devices brought in from outside the country.
