== BACKGROUND==


<p>&nbsp;&nbsp;&nbsp;&nbsp;
The distribution is known as The Amnesic Incognito Live System (TAILS). The goal of the distribution is to provide anonymity for the user and thus targets any consumers that require a higher level of privacy when using the internet and do not want to leave traces of their activity on the host file system. TAILS is an extension of the Debian GNU/Linux distribution system.
</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;
To achieve online anonymity, TAILS uses the Tor Network. The Tor Network is an open network that is accessible through free software. Tor is designed to make it difficult for anyone to trace your internet traffic. It uses a network of virtual tunnels to protect the user from “traffic analysis” (eavesdropping, IP spoofing, ARP spoofing, etc...). To combat these attacks it sends your data packets as multi-hop circuit of relays. Each relay only knows the address of the relay that provided the data and the relay it will provide the data too. This effectively erases the track back to the sender. Any eavesdropper will only be able to trace the message back to the relay before. One drawback is that the Tor network does not encrypt data from relay to relay only from the sender to the first relay and from that relay back to the sender. This prevents the eavesdropper from being able to view your data at the first relay but does not prevent them from viewing your data at other relays. Although the onus is on the website the user is communicating to provide the end-to-end protection TAILS does provide this protection when using IRC or Email through software that comes with the system. Another drawback is that most if not all modern Web Browsers use JavaScript, Adobe Flash and Cookies, these have been proven to occasionally bypass the anonymity feature. To combat this TAILS provides its own Web Browser based of Firefox called Iceweasel. Unfortunately some sites will not work with it due to its limitations.
</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;
To help protect against leaving traces on the host computer TAILS runs as an independent operating system unless made to do otherwise. TAILS is a Livedistro that runs off a bootable USB or CD (USB is faster) requiring no installation on the host PC. The only memory TAILS accesses is RAM which is overwritten on PC shutdown (unless the shutdown is abrupt, such as in a power failure) leaving no trace on the system. If you choose to do so you can run TAILS through as a virtual machine but this negates the above protection feature as both the virtual machine and the host OS will leave traces on the host PC. The other drawback is that as you are not using the host PC file storage system you need to use a separate storage system such as another USB drive to save any data that you work on while in TAILS.
</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;
TAILS can be obtained for free from the internet. The latest version is 0.8.1 and it was released on October 16th, 2011. It downloads as an ISO image of 579 Mb in size. The home website for TAILS has an interesting feature where it allows the user to verify that the ISO they downloaded is authentic as the genuine version is encoded with a cryptographic signature. The user can either do this through a check through Firefox, using an add-on, or through software known as Gpg4win which is essentially an encryption and decryption software. This just shows the level of commitment the developers have to user privacy and security.
</p>
== INSTALLATION/STARTUP ==
<p>&nbsp;&nbsp;&nbsp;&nbsp;
Once the user has downloaded the ISO image they will need to make the USB or CD key bootable from that ISO. I used the USB approach and used the Universal USB Installer software (version 1.8.6.8). Once the USB key has been created the user simply uses makes the host PC boot to the USB key upon restart. Upon restart the user is presented with a boot menu where they can select their language. One the distribution system loads the user is presented with a desktop UI and TAILS automatically launches an Iceweasel and tests the TOR connection.

<p>&nbsp;&nbsp;&nbsp;&nbsp;
The actual start-up of the distribution system from the USB key was very fast. The load time was approximately 30-45 seconds once the language at the boot menu is chosen. As TAILS is meant to run as a Livedistro system I did not use any virtualization software to get it running (although the option is there if you so choose) and as such do not have a screen shot of the actual loading process.
