  • Using network bound disk encryption with Stratis

    In an environment with many encrypted disks, unlocking them all is a difficult task. Network bound disk encryption (NBDE) helps automate the process of unlocking Stratis volumes. This is a critical requirement in large environments. Stratis version 2.1 added support for encryption, which was introduced in the article “Getting started with Stratis encryption.” Stratis version 2.3 recently introduced support for Network Bound Disk Encryption (NBDE) when using encrypted Stratis pools, which is the topic of this article.

    [...]

    One of the main challenges of encrypting storage is having a secure method to unlock the storage again after a system reboot. In large environments, typing in the encryption passphrase manually doesn’t scale well. NBDE addresses this and allows for encrypted storage to be unlocked in an automated manner.

    At a high level, NBDE requires a Tang server in the environment. Client systems (using Clevis Pin) can automatically decrypt storage as long as they can establish a network connection to the Tang server. If there is no network connectivity to the Tang server, the storage would have to be decrypted manually.

    The idea behind this is that the Tang server would only be available on an internal network, thus if the encrypted device is lost or stolen, it would no longer have access to the internal network to connect to the Tang server, therefore would not be automatically decrypted.

    For more information on Tang and Clevis, see the man pages (man tang, man clevis) , the Tang GitHub page, and the Clevis GitHub page.
