The most shadowy and disparaged of all the US spy agencies, the National Security Agency (NSA), has released a version of the Linux operating system that has been modified to provide extremely high levels of security. Tech industry companies have assisted in the creation of the prototype built to make it more difficult to bypass application security mechanisms and limit damages when incursions do occur.
According to copy on the NSA’s Website, “This work is not intended as a complete security solution for Linux. Security-enhanced Linux is not an attempt to correct any flaws that may currently exist in Linux. Instead, it is simply an example of how mandatory access controls that can confine the actions of any process, including a superuser process, can be added into Linux.”
