Iran Filters and Jams Internet to Combat the Opposition

Arash Aramesh

Among all the countries in the Middle East and Persian Gulf, Iran has the most Internet users. For the past six months, Iran’s young population has used this effective medium as a tool for the opposition movement to organize events and demonstrations.
Harvard’s Berkman Center for Internet and Society says Iran is home to one of the world’s richest and most varied blogospheres, with major clusters for secularist and reformist politics as well as conservative politics, for “CyberShia” religious discussion as well as Persian poetry appreciation.

At the same time, the OpenNet Initiative says Iran has one of the world’s most extensive Net filtering systems, on par with China’s. Iranians, however, manage to get around the filters by using proxy servers. Many major Iranian news sources such as Voice of America and Radio Farda—both funded by the U.S. government—make daily announcements informing their viewers and listeners how to use proxies.

In order to combat the use of Internet by the opposition, the authorities have purchased sophisticated technology from Western companies to filter undesired information and monitor the activities of Iran’s 23 million Internet users. This has caused a backlash in Iran against these companies, chief among them are Finland’s Nokia and Germany’s Siemens. The Wall Street Journal provided some good information on this topic outlining the purchases made by the Iranian authorities and how these new sophisticated technologies help them monitor the activities of the opposition.

The Iranian government, Iran’s only Internet service provider, plans ahead of demonstrations and shuts down access to the Internet and, at times, cell phone communication. This limits the opposition’s ability to organize and reach a large number of people. For instance, prior to the Student Day protests on December 7, the Iranian authorities reduced Internet speeds in the country to such a slow pace that it was impossible for most to use the Internet effectively.

The Iranian government has a history of shutting down means of communication in order to prevent mass demonstrations. More than the Internet, the Iranian masses use their cell phones and the SMS feature. Political jokes and opposition articles circulate freely from phone to phone via SMS. After the disputed results of the June 12 election were announced, the Iranian authorities, fearing large gatherings and demonstrations, shut down the entire SMS network in the country. SMS services in Tehran and some major cities were down even two weeks after the election. One article describes how SMS networks were shut down by the government from June 11, a day before the election, and were not reactivated until ten days later.

In order to retaliate against the government’s efforts at silencing the opposition on the Internet, opposition activists wave what is called a DOS Attack, sending an enormous amount of traffic to overload the server. OpenNet outlines how the government cracks down on digital means of organization and how the opposition responded to it. According to OpenNet, restricted Internet access made it extremely difficult for news and photos to reach the outside world, but the opposition managed to do it anyway.
