Safe System

Tails Logo

We use Ubuntu Desktop Linux for everyday personal computing. But for some more sensitive tasks a separate “Safe System” is needed.

  • Creating a Safe Storage to save highly sensitive data (i.e. password and encryption keys);
  • Use the Internet anonymously and circumvent censorship;
  • Leave no trace of the thins you are doing on the computer you are using;

The “Safe System” is not suitable for everyday work, as it lacks features and comfort, but provides more security.

For this kind of tasks we use Tails, the amnesic incognito live system.

It is a complete Linux desktop system, bootable from a DVD or USB-Stick that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.

You can read more on trusting tails on their own website.

The ISO image is cryptographically signed by the Tails developers. The key used to sign the image, is signed by several Linux Debian developers. Debian is the Linux system, which Ubuntu is based on.

By using Ubuntu we already put a lot of trust in the Debian developers.

Install debian developer keys in to our system:

The keys are saved in a GnuPG keyring file /usr/share/keyrings/debian-keyring.gpg.

Install them on our personal keyring.

$ gpg --verify-files tails-i386-1.3.iso.sig

Download and import the signing key to your personal keyring:

wget -O - https://tails.boum.org/tails-signing.key | gpg --import

Verify the ISO image:

$ cd Downloads
