Lightweight Portable Security (LPS-Public) is a bootable live CD designed by the Department of Defense so that government employees can access data from a public computer without worrying about security violations.
Booting from a CD and executing from system RAM, the lightweight Linux distro should be safe from spyware or viruses, and since the LPS-Public does not mount to the hard drive of the host computer no trace of work activity is logged.
LPS-Public includes features designed to allow productive use of the Internet and CAC- or PIV-restricted Government websites from home or while traveling. LPS-Public comes preconfigured with a smart card-enabled Firefox web browser with Java and Flash support, Encryption Wizard-Public, a PDF viewer, a file browser, remote desktop software (Citrix, Microsoft or VMware View), SSH client, and the ability to use USB flash drives. This build does not contain any FOUO material or any customized software.
LPS-Public Deluxe adds OpenOffice software, which is a Microsoft Office-compatible suite of office applications, and Adobe Reader, which allows PDF files to be digitally signed.
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.
LPS differs from traditional operating systems in that it isn't continually patched. LPS is designed to run from read-only media and without any persistent storage. Any malware that might infect a computer can only run within that session. A user can improve security by rebooting between sessions, or when about to undertake a sensitive transaction. For example, boot LPS immediately before performing any online banking transactions. LPS should also be rebooted immediately after visiting any risky web sites, or when the user has reason to suspect malware might have been loaded. In any event, rebooting when idle is an effective strategy to ensure a clean computing session. LPS is updated on a regular basis (at least quarterly patch and maintenance releases). Update to the latest versions to have the latest protection.
