How to use Linux for secure computing

1. Installing a Clean Linux OS with no modifications, program add-ons, etc, helps prevent keyloggers, spyware, and other malware from being installed. Burning Linux Live CD to a write only media such as a CD/DVD or a Kanguru USB drive with Write protect switch, helps prevent any changes to a virgin Linux distribution. Keep in mind that no bookmarks, password managers, etc would be accessible.

The CD versions do take many minutes to boot up and ask you if you want to try Linux, so the USB route is definitely preferred.

2. Ubuntu Linux is a user-friendly Linux distribution and a good bet for most Linux newbies and novices. Try it on USB drive or burn it to a CD, there is no need to install the operating system on to a hard disk. We recommend you use an LTS or long term support version of Ubuntu so that there is long term stability to your Linux choice. (10.04 LTS is a good choice) The other popular Linux distribution is known as Fedora, it is more data center, server-oriented. If you are reading this, Ubuntu is the way to go.

3. Unetbootin is a useful utility that creates a bootable live USB drive or flash drive from Linux distributions, such as Ubuntu, Fedora, etc. It even downloads the Linux distribution automatically.   This program run on Windows, Mac OS X, and Linux, but the resulting USB drives are bootable only on PCs.

4. Backtrack is a specialized Linux distribution for penetration testing. It is filled with useful tools to test the security of computers and networks. You can use Unetbootin to install it on a USB drive. Backtrack is designed for security experts, it is not easy to learn.

5. Tails is a preconfigured Linux distribution full of security essentials. It includes the Iceweasel browser, which utilizes the Tor network for anonomys browsing. HTTPS Everywhere, Adblock Plus, and NoScript are preloaded, to increase security and block ads.

Tor is only as secure as its exit nodes. If a hacker creates an exit node, they can ease-drop on all communications.

Claws email client with OpenPGP is included for secure email. LUKS is utilized for automatic file encryption.

Does this make you want to try Linux? Have you used a Live CD?
