North Korea's Secret Computer System - Red Star OS
German computer experts have been taking a closer look at North Korea's own secret computer operating system, Red Star OS. Until now, not much has been known about it.
The Communist country runs its own operating system - an altered version of Linux. It looks and feels like a normal operating system with all the apps and software . But Red Star OS is controlled by the state . A closer look shows that it uses technology that allows authorities to spy on its citizens.
The system detects if a user wants to change thing, then automatically shuts down and reboots.It also has special security features that prevent users from other countries from hacking into it. Messages are encrypted to guarantee safe transport. Files are watermarked so that the government can see if and how users have changed them. Such security also allows authorities to find out who downloads pirated music and movies from the west.
North Korea has been working on its own operating system for years, in an effort to replace the ageing Windows XP , which many people still have installed. But nobody really knows how many North Koreans are using Red Star OS.
The communist country controls its citizens like no other state in the world. North Korea is isolated technologically from the rest of the world.There are no internet connections to the outside . Social media and other websites cannot be accessed from within.
