Lightweight Portable Security (LPS), created by USA’s Department of Defence, is a small Linux live CD focusing on privacy and security, for this reason, it boots from a CD and executes from RAM, providing a web browser, a file manager and some interesing tools. LPS-Public turns an untrusted system into a trusted network client.
The environment that it offers should be largely resistant to Internet-borne security threats such as viruses and spyware, particularly when launched from read-only media such as a CDROM. The LPS system does not mount the hard drive of the host machine, so no trace of work activity can be written to the local computer.
If you’ve been doing online banking on the same computer which you use for general browsing and social networking, you need to switch your banking activities to this.
