Lightweight Portable Security (LPS) is a lightweight, portable version of Linux that allows the user to turn any unmanaged computer system into a trusted end-node by securely booting a trusted operating system. LPS has also been designed to allow users in untrusted environments to remotely access trusted computing resources. The trusted computing resources could include your personal financial institution, your workplace, or other sensitive network application/activity. LPS can also be used as a safe way to interact with untrusted web resources. LPS is designed to be read-only and does not provide access to local hard disk drives (though it does support saving documents to USB flash sticks). LPS is designed with the mobile or ad hoc telecommuting user in mind. LPS may include a few varieties of thin-client software, VPN clients, and a DoD CAC-enabled web browser.
Sounds like a typical Linux live CD, doesn't it. Maybe one with an emphasis on security and a light footprint so it will boot quickly. Maybe like ZooT aLLures' Wyoming Puppy Linux, a home brew "puplet" (respin) of Puppy Linux with an emphasis on security. Wyoming Puppy Linux is so low profile it doesn't even have a home page. But you can download it.
Emphasis on security, yes. Typical home brew, hardly. For one thing, notice the milspeak in that announcement. Lightweight Portable Security is a US Air Force project. One thing conspicuously absent from the LSP web site is a downloads page.
I do like the idea that some guy in Boondocks, Wyoming (or is he?) can distribute a secure live CD on an even footing with the US Air Force. Now, that's cool!
