</details><p><strong>LUKS</strong> est un format standard sur disque pour le chiffrement des disques durs. Il utilise le chiffrage par mappeur de périphérique (dm-crypt) et est implémenté en tant que module du noyau pour gérer le chiffrage au niveau du périphérique de bloc.<br />
<strong>LVM</strong> est un outil de gestion des volumes logiques qui comprend l’allocation de disques, le striping, le mirroring et le redimensionnement des volumes logiques.</p>
<p><strong>LUKS</strong> peut être utilisé avec <strong>LVM</strong> pour créer des volumes extensibles/chiffrés. L’une des options les plus robustes et les plus extensibles consiste à créer un volume chiffré à l’intérieur d’un volume logique.</p>
<ul>
<li>créez un groupe de volumes LVM d’un ou plusieurs disques</li>
<li>utiliser le groupe de volumes pour créer des volumes logiques LVM</li>
<li>appliquer le chiffrage au système de fichiers des volumes logiques LVM</li>
</ul>
<p><em>L’utilisation d’un volume logique permet de monter les disques au démarrage et peut être étendu dynamiquement sans sacrifier la sécurité.</em></p>

<p>A ce stade, nous avons terminé. Redémarrez votre machine et elle vous demandera votre YubiKey et vous permettra de déverrouiller votre patition racine chiffrée LUKS avec elle. Si vous n’avez pas votre YubiKey, le message suivant apparaîtra :</p>
<p><code class="language-plaintext highlighter-rouge">Security token not present for unlocking volume root (nvme0n1p3_crypt), please plug it in.</code></p>
<p>Au bout d’environ 30 secondes, le délai d’attente est dépassé et le message suivant s’affiche :</p>
<p><code class="language-plaintext highlighter-rouge">Timed out waiting for security device, aborting security device based authentication attempt.</code></p>
<p>Ensuite, il vous permettra de déverrouiller la partition à l’aide d’un mot de passe (ou d’une clé de récupération).</p>
<p>En cas de problème, ajoutez <code class="language-plaintext highlighter-rouge">rd.break=initqueue</code> à la ligne de commande du noyau, et dracut entrera dans un shell avant de tenter de monter les partitions. Vous pouvez monter manuellement le disque en utilisant la commande suivante :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code># /usr/lib/systemd/systemd-cryptsetup attach root /dev/nvme0n1p2
</code></pre></div></div>

<p><em>Firejail est un logiciel de sandboxing pour les systèmes d’exploitation Linux. Il permet d’exécuter des applications dans un environnement isolé du système d’exploitation hôte.
Cela fonctionne quelque soit le type d’application (en ligne de commande ou graphique)<br />
Le principe de Firejail est de créer un environnement de sécurité en lançant une application dans une boîte isolée (sandbox) où elle ne peut accéder qu’aux ressources autorisées. Ce logiciel repose sur les fonctionnalités du noyau Linux.</em></p>
