The latest version of this distribution can be downloaded from Softpedia
Lightweight Portable Security (LPS) 1.5.1, a thin Linux operating system that creates a secure end node from trusted media on almost any Intel-based computer (PC or Mac), has been released and is now available for download.LPS 1.5.1 is not your regular Linux distribution, and it has been built with one purpose in mind: to be as secure as possible and to not leave any trace of the users, which is rather strange because this is an operating system built by the US Air Force.
Users will not need any administrator access to run the system and the distribution is using mostly web-based applications, which means that it can be used from a CD or USB without having to mount the local hard drive.
“LPS-Public allows general web browsing and connecting to remote networks. It includes a smart card-enabled Firefox browser supporting CAC and PIV cards, a PDF and text viewer, Java, and Encryption Wizard - Public.”
“LPS-Public turns an untrusted system (such as a home computer) into a trusted network client. No trace of work activity (or malware) can be written to the local computer. Simply plug in your USB smart card reader to access CAC- and PIV-restricted US government websites,” reads the official website.
The previous version, Lightweight Portable Security (LPS), made some very important changes and one of the most notable was the switch to Xfce, a lighter and faster desktop environment than the one that was previously used. A number of other features were also added, like NVIDIA Optimus graphics multiplexing support, IPv6 DHCP support, and platform drivers for some netbooks.
Lightweight Portable Security (LPS) 1.5.1 is based on Linux kernel 3.10.35, which is a long-term support version. The developers haven't modified the kernel and they kept the one that everyone can download and use.
Also, the DNSCrypt feature has been fixed, users can now employ the Printing feature again, Power Management controls have been implemented, support for Express Card CCID smartcard readers has been added, Encryption Wizard has been updated to version 3.4.1, Mozilla Firefox has been updated to version 24.4.0 ESR (extended support release), Adobe Flash Player has been updated to version 22.214.171.1240, OpenSSH has been updated to version 6.6p1, and Mozilla Thunderbird has been updated to version 24.4.0.
A complete backlog of improvements and fixes can be found in the official changelog. Download Lightweight Portable Security (LPS) 1.5.1 right now from Softpedia.
