Outside of the U.S., there are several “national” Linux distributions. These include China’s Red Flag Linux; Turkey’s Pardus, and the Philippines’ Bayahnian. Other countries, like Russia, are on their way to moving their entire IT infrastructure to Linux and open-source software. In the U.S., the government, especially the military, makes use of Linux all the time. Indeed, Security-Enhanced Linux (SELinux), the most popular software set for hardening Linux against Linux is sponsored by the National Security Agency. But, there hasn’t been a national American Linux desktop distribution… until now.
The Software Protection Initiative (SPI) under the direction of the Air Force Research Laboratory and the US Department Of Defense recently created Lightweight Portable Security (LPS). Like the name indicates, this is a small Linux desktop distribution that’s designed for secure use.
LPS is designed to boot from a CD or USB pen-drive on any Intel-based computer. It doesn’t install anything. It’s designed solely to run solely in memory and to leave no traces behind when you’re doing running it.
