The Iranian government, determined to limit Western influence and defend itself against cyberattacks, appears to have laid the technical foundations for a national online network that would be detached from the Internet and permit tighter control over the flow of information.
The concept of a self-contained network has been reverberating within Iran for almost a decade and has often been treated with skepticism, given the significant investment in infrastructure and security that would be required. But Iranian officials and outside experts say that development of the network has accelerated following cyberattacks aimed at the country’s nuclear program.
