Data breaches and cyber threats are becoming increasingly common and securing your personal and professional information has never been more critical.

Users transitioning from Windows to Linux through the Upgrade to Freedom campaign can use openSUSE’s tools to protect sensitive data, which include full disk encryption (FDE).

Full disk encryption during installation ensures maximum security. It safeguards all data on your hard drive by encrypting it and makes it unreadable without an decryption key. This level of protection is vital for preventing unauthorized access if your laptop or desktop is lost or stolen.

FDE with openSUSE is both user-friendly and powerful. The setup with advanced security features is easy.

For users seeking feature parity with Windows BitLocker, openSUSE offers Full Disk Encryption (FDE) secured by a TPM2 chip or a FIDO2 key. This advanced setup enhances security by storing encryption keys within the TPM, which ensures that only a trusted system configuration can unlock the disk. For a step-by-step guide on enabling this feature, read the Quickstart in Full Disk Encryption with TPM and YaST2 article.

Here’s a step-by-step guide to set up FDE on your system:

Step 1: Download and Boot openSUSE

• Visit get.opensuse.org to download the latest version of openSUSE Leap or Tumbleweed.
• Create a bootable USB drive using tools like balenaEtcher or another image writer.
• Restart your computer and boot from the USB drive to begin the installation process.

Step 2: Configure Encryption During Installation

• Once the installer starts, select your preferred language and keyboard layout.
• In the partitioning setup, choose Guided Setup with Encrypted LVM.
• Set a strong passphrase for encryption. This passphrase will be required every time the system boots. - Use a mix of upper and lower case letters, numbers and special characters for optimal security.
• Proceed with the installation as directed by the installer.

Step 3: Verify Encryption Settings

After installation is complete and the system restarts, you’ll be prompted to enter your encryption passphrase. Once entered, openSUSE tools will decrypt the disk and boot normally. To confirm encryption is active:

• Open a terminal or console.
• Run the command lsblk -f to verify that your disk is listed with the encryption type (e.g., crypto_LUKS).

The output might look something similar to the following:

NAME        FSTYPE      FSVER LABEL UUID                                   FSAVAIL FSUSE% MOUNTPOINT sda ├─sda1      ext4        1.0     4a83v1e1-e8d2-4e38-815d-fd79j194f5   25G    30%    / └─sda2      swap        1           d2e18c23-9w4b-4d26-p1s2-cm2sd64tx9de sdb └─sdb1      crypto_LUKS 1           10bb2vca-81r4-418b-a2c4-e0f6585f2c7a └─luks    ext4        1.0         8a9wka1b-7e9c-1a1f-a9f7-3c82x1e4e87f   150G    10%    /mnt/data 

Step 4: Regular Backups

While FDE protects your data, it does not prevent data loss from hardware failure or accidental deletion. Regularly back up your data to an encrypted external drive or a secure cloud service to ensure its safety.

Enhanced Security for Modern Challenges

Setting up full disk encryption on openSUSE not only protects your data but also aligns with the Upgrade to Freedom campaign’s mission of empowering users to maintain control over their hardware and privacy. By combining open-source software with good security practices, openSUSE ensures that users can confidently embrace a more secure digital future.

For additional guidance and community support, visit the openSUSE forums or join discussions at your local Linux user group.

Please be aware that some hardward configurations may require additional drivers or BIOS settings adjustments for full disk encryption to fully function properly. Check your device’s compatibility and update your firmware before proceeding.

Always regarded as the best of Japan's feudal samurai castles, Himeji dates from the 14th century and was remodelled several times. It is largely original, built of wood, serving earthquakes and bombing during WWII. It recently underwent a long restoration. Visit in January, as we did, and you have it almost to yourself.
