Top-level domain: .sd Internet censorship and surveillance Sudan was listed as engaged in substantial Internet filtering in the social and Internet tools areas, in selective filtering in the political area, and as no evidence of filtering in conflict/security area by the OpenNet Initiative in August 2009. Sudan openly acknowledges filtering content that transgresses public morality and ethics or threatens order. The state's regulatory authority established a special unit to monitor and implement filtration; this primarily targets pornography and, to a lesser extent, gay and lesbian content, dating sites, provocative attire, and many anonymizer and proxy Web sites. The government monitors Internet communications, and the National Intelligence and Security Services (NISS) reads e-mail messages between private citizens. The National Telecommunications Corporation blocks some Web sites and most proxy servers deemed offensive to public morality. While there generally are no restrictions on access to news and information Web sites, authorities regularly block access to YouTube. During the June and July 2012 antigovernment demonstrations, authorities blocked access to several popular online discussion forums. Security agencies also arrested several bloggers during this period, and commentators speculated the government used social media to track and arrest protesters. The interim national constitution provides for freedom of thought, expression, and of the press “as regulated by law”; however, the government severely restricts these rights. Individuals who criticize the government publicly or privately are subject to reprisal, including arrest. Journalists are subjected to arrest, harassment, intimidation, and violence due to their reporting. The government, including NISS, practices direct prepublication censorship of all forms of media. Journalists also practice self-censorship. NISS resorts to legal action against journalists, bringing libel lawsuits for stories critical of the government and security services. The Supreme Court in December 2011 overturned a lower court decision against several of the accused journalists, but NISS petitioned for a review of the higher court's decision. The Supreme Court rejected the NISS appeal in September 2012, but the security service continued to pursue defamation cases against several other journalists. The interim national constitution and law prohibit arbitrary interference with privacy, family, home, or correspondence, but the government routinely violates these rights.
