Iran
The Islamic Republic of Iran continues to expand and consolidate its technical filtering system, which is among the most extensive in the world. A centralized system for Internet filtering has been implemented that augments the filtering conducted at the Internet service provider (ISP) level. Iran now employs domestically produced technology for identifying and blocking objectionable Web sites, reducing its reliance on Western filtering technologies. The regulatory agencies in Iran charged with policing the Internet continue to expand. The Revolutionary Guard has begun to play an active role in enforcing Internet content standards. In conjunction with expansive surveillance, this increase in regulatory attention exacerbates an online atmosphere that promotes self-censorship and discourages dissenting views. The blocking of political Web sites during the 2009 presidential elections energized opposition to Internet censorship within Iran and has brought fresh attention to the issue of press controls.
