It is a platform-independent disk encryption specification and the de facto disk encryption standard for Linux systems. LUKS is a standard hard drive encryption technology for major Linux systems including Ubuntu. ![]() In this tutorial, we will focus on how to enable full disk encryption on Ubuntu 22.04 using LUKS. This type of encryption targets individual files and directories, but not the entire hard disk.īoth full disk encryption and file level encryption can be used simultaneously to achieve a higher level of data protection. File Level EncryptionĪs the name infers, file level encryption happens at the file system level. Learn more about the benefits of FDE, and five reasons you should consider requiring it in your organization. Implementing FDE guarantees data privacy and security for all the files from unauthorized users or anyone with malicious intent. During booting, a passphrase or secret key is required to unlock the drive before logging in with your user account credentials. In full disk encryption, also known as hard drive encryption, the entire hard drive or volume - including all the files - is protected. ![]() There are two major types of encryption in a computer: Full Disk Encryption (FDE) and File Level Encryption (FLE). This key should always remain a secret to the person authorized to access the data. Data is converted from plain text to ciphertext using a special mathematical algorithm that renders the data unreadable unless the encryption key is provided. ![]() Disk encryption is one of the best ways to mitigate this risk.Įncryption is the process of encoding data. The compromise of a device can prove costly if it contains sensitive company information, especially when organizations have compliance requirements. Security-minded system administrators prioritize taking all the necessary measures to safeguard confidential and protected data.
