<p>See how we implement this [[memory
erasure|contribute/design/memory_erasure]], for example, if you want to
implement this feature outside of Tails.</p>

<p>In a <a
href="https://www.forensicfocus.com/stable/wp-content/uploads/2011/08/cold_boot_attack_for_forensiscs1.pdf">research
report from 2011</a>, Defense Research and Development Canada concluded that
cold boot attacks can be useful in some cases to acquire data in memory but are
not a panacea and have many drawbacks dictated by the laws of physics, which
cannot be overcome by the technique. The authors recommend to only use cold
boot attacks as a last resort when all other avenues have been exhausted.</p>

<p>As far as we know, cold boot attacks are not a common procedure for
data recovery.</p>

After a computer is powered off, the data in RAM disappears rapidly, but it can remain in RAM up to several minutes after shutdown. An attacker having access to a computer before the data in RAM disappears completely could recover important data from your session.
Après extinction d'un ordinateur, les données stockées dans la mémoire vive disparaissent rapidement, mais peuvent y rester jusqu'à plusieurs minutes après extinction. Un attaquant ayant accès à l'ordinateur avant qu'elles n'en disparaissent complètement pourrait récupérer des données importantes de votre session.

While using a computer, all the data manipulated is written temporarily in [[!wikipedia Random-access_memory desc="RAM"]]: texts, saved files, but also passwords and encryption keys. The more recent the activity, the more likely it is for the data to still be in RAM.
Lors de l'utilisation d'un ordinateur, toutes les données manipulées sont écrites temporairement dans la [[!wikipedia_fr Mémoire_vive desc="mémoire vive"]] : textes, fichiers sauvegardés, mais aussi mots de passe et clés de chiffrement. Plus l'activité est récente, plus il y a de chance que les données soient encore dans la mémoire vive.

Moreover, an attacker having physical access to the computer *while Tails is running* can recover data from RAM as well. To avoid that, learn the different methods to [[shutdown Tails|doc/first_steps/shutdown]] rapidly.
De plus, un attaquant ayant un accès physique à l'ordinateur *pendant l'utilisation de Tails* peut récupérer des données de la mémoire vive également. Pour éviter cela, apprenez les différentes méthodes pour [[éteindre Tails|doc/first_steps/shutdown]] rapidement.
