Ubuntu 22.04<\/a> and you want to enable full disk encryption, you\u2019re required to reinstall it. You cannot fully encrypt it once it is installed. You can only encrypt directories or partitions post-installation.<\/p>\n\n\n\nIf you forget your encryption passphrase, all your data will be inaccessible. As such, it is recommended to pick one that you can easily remember or store on a password vault or manager. Better yet, if you have used a complex password, you can note it down somewhere and keep it under lock and key.<\/p>\n\n\n\n
Additionally, before starting this process, be sure to backup any critical data that could potentially be lost during the reinstallation process.<\/p>\n\n\n\n
Getting Started<\/h2>\n\n\n\n We will skip the few installation steps on Ubuntu 22.04 and head straight to the \u201cInstallation Type<\/strong>\u201d step that requires you to select your preferred disk partition mode.<\/p>\n\n\n\nTwo options will be presented. The first one (the default option) is \u201cErase disk and install Ubuntu<\/strong>\u201d which wipes out all the existing data and automatically partitions the drive. The second option is \u201cSomething else<\/strong>\u201d which is used to manually configure the disk partitions yourself. Please note that you will not be able to enable full disk encryption by selecting the second option.<\/p>\n\n\n\nSelect the first option: \u201cErase disk and install Ubuntu<\/strong>\u201d and click the \u201cAdvanced features<\/strong>\u201d button as indicated.<\/p>\n\n\n\n <\/figure>\n\n\n\nOnce you click the \u201cAdvanced features<\/strong>\u201d button, a pop-up appears. Be sure to select \u201cUse LVM with new Ubuntu installation<\/strong>\u201d and the \u201cEncrypt the new Ubuntu installation for security<\/strong>\u201d options.<\/p>\n\n\n\nThen click \u201cOK<\/strong>.\u201d<\/p>\n\n\n\n <\/figure>\n\n\n\nNext, assuming you have already backed up any important data, click \u201cInstall Now<\/strong>.\u201d<\/p>\n\n\n\n <\/figure>\n\n\n\nDisk encryption requires a security key in order to access your files each time your device boots. In this step, provide a strong security key or passphrase.<\/p>\n\n\n\n
You can also enable a recovery key which enables a user to access the encrypted disk if they forget their password, or if the disk needs to be installed on a new device.<\/p>\n\n\n\n
Then click \u201cInstall Now<\/strong>.\u201d<\/p>\n\n\n\n <\/figure>\n\n\n\nOn the pop-up dialogue that appears, click \u201cContinue<\/strong>\u201d to write changes to the disk.<\/p>\n\n\n\n <\/figure>\n\n\n\nFrom here, continue with the installation process until the end, and finally, reboot the system. Provide the security key that you generated and hit ENTER prior to logging in.<\/p>\n\n\n\n <\/figure>\n\n\n\nThe secret key unlocks your drive thereby granting you access to your system.<\/p>\n\n\n\n <\/figure>\n\n\n\nFrom here, you can log in to your new Ubuntu installation by providing your user account\u2019s password and pressing ENTER.<\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n In this guide, we walked you through the implementation of full disk encryption using LUKS on Ubuntu 22.04. FDE provides a robust way to safeguard your data in case of theft or accidental loss of your device. <\/p>\n\n\n\n
Encryption is just one approach to ensuring the privacy and safety of your data. Therefore, you should not relax enforcing other data protection measures such as firewalls, identity and access management (IAM), and Zero Trust controls such as multi-factor authentication (MFA).<\/p>\n\n\n\n
JumpCloud\u2019s open directory platform is available to easily implement full disk encryption throughout your entire fleet. Pre-built policies make it possible to achieve full disk encryption for Windows and macOS devices, with granular control and visibility for BitLocker.<\/p>\n\n\n\n <\/figure>\n\n\n\nLinux devices can also be managed and monitored for encryption status.
