The number of Brazilians using the Internet has increased dramatically since 2000. Internet access remains predominantly in developed, urban areas, where Internet cafes — frequented mainly by Brazilians from lower socioeconomic groups — “connect” nearly half of all users. Brazilian users most frequently access social media, especially social networking sites (SNS) like Orkut, a Google-owned site comparable to Facebook, and Twitter. Facebook has tried to challenge Orkut’s market dominance, with mixed results. Blogging is also a popular form of Internet communication, while YouTube is the most widely used video website.

Cyberspace Policy Review
The President directed a 60-day, comprehensive, “clean-slate” review to assess U.S. policies and structures for cybersecurity. Cybersecurity policy includes strategy, policy, and standards regarding the security of and operations in cyberspace, and encompasses the full range of threat reduction, vulnerability reduction, deterrence, international engagement, incident response, resiliency, and recovery policies and activities, including computer network operations, information assurance, law enforcement, diplomacy, military, and intelligence missions as they relate to the security and stability of the global information and communications infrastructure. The scope does not include other information and communications policy unrelated to national security or securing the infrastructure. The review team of government cybersecurity experts engaged and received input from a broad cross-section of industry, academia, the civil liberties and privacy communities, State governments, international partners, and the Legislative and Executive Branches. This paper summarizes the review team’s conclusions and outlines the beginning of the way forward towards a reliable, resilient, trustworthy digital infrastructure for the future.
