How to Fully Encrypt Data on Ubuntu 20.04Īs mentioned earlier, you can only fully encrypt your hard drive or SSD during the installation process. Thankfully, Ubuntu 20.04 offers an option that allows you to fully encrypt your hard disk or SSD during the installation process, which this guide will walk you through. It encrypts all the partitions including swap space, system partitions and every bit of data stored on the block volume.

Note that full disk encryption is only achieved during the installation of the Ubuntu Desktop operating system. With LUKS, disk encryption is enabled during the installation of the operating system or post-installation. LUKS provides a platform-agnostic standard of encryption that not only guarantees compatibility among various Linux distributions but also ensures that they implement password management in a well-documented and secure manner. It’s free, supports the management of multiple keys and passwords, and secures all the data stored on your hard drive from unauthorized access.

It is used for encrypting entire block devices and is therefore ideal for encrypting hard disk drives, SSDs, and even removable storage drives. LUKS, short for Linux Unified Key Setup, is a standard hard drive encryption technology for major Linux systems including Ubuntu. Disk Encryption on Ubuntu 20.04 using LUKS As employees continue to work from home, either permanently or in a hybrid workplace scenario, this becomes an essential security configuration in case an employees device gets lost or stolen, or when someone may try to access a device using a bootable live medium. The disk cannot be unlocked or accessed without a password or the secret key that was used for encryption.įull disk encryption (FDE) guarantees data privacy by preventing unauthorized access to your hard drive by hackers and other nefarious parties when at rest. A special algorithm is used to encrypt a single disk partition, multiple partitions, or the entire physical drive. The concept of hard drive encryption, or simply disk encryption, follows the same principle. The only parties that can access encrypted data are those with the specified decryption key or a password (which acts as the key). What is (Full) Disk Encryption?Įncryption is the process of converting plain text data into ciphertext, which is an unreadable format using a special mathematical algorithm.

One of them is enabling full disk encryption on their drive. There are various steps you can take to safeguard Linux devices from potential breaches.

Source code stored on a Linux laptop could fall prey to malicious individuals or perhaps there is PII stored on the laptop in a local file or database regardless of the individual use case, ensuring that your data is secure is critical. In a worst-case scenario you may find your hard drive completely wiped, with critical files inaccessible and possibly stolen without much evidence left behind.

The default configurations chosen during the first installation are not enough to harden your device, and unpatched Linux systems and the use of outdated software can significantly increase the chances of a breach. No device is foolproof, and like many things in your environment, your Linux system is as secure as its weakest point. Though some may argue that Linux is the most secure and stable operating system, it can still fall prey to the same misconfigurations and user errors that plague users of Mac and Windows devices. Criminal hackers are increasingly more sophisticated in their attack vectors and constantly inventing new ways of bypassing even the most secure systems. Device security is one of the primary concerns that security professionals, developers, and other IT professionals have in the face of a growing number of cyber threats.
