From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Do you encrypt your drives and why or why not? (lemmy.ml)

I was recently intrigued to learn that only half of the respondents to a survey said that they used disk encryption. Android, iOS, macOS, and Windows have been increasingly using encryption by default. On the other hand, while most Linux installers I've encountered include the option to encrypt, it is not selected by default.

Whether it's a test bench, beater laptop, NAS, or daily driver, I encrypt for peace of mind. Whatever I end up doing on my machines, I can be pretty confident my data won't end up in the wrong hands if the drive is stolen or lost and can be erased by simply overwriting the LUKS header. Recovering from an unbootable state or copying files out from an encrypted boot drive only takes a couple more commands compared to an unencrypted setup.

But that's just me and I'm curious to hear what other reasons to encrypt or not to encrypt are out there.

If someone can execute arbitrary code on my computer, it doesn't matter that the disk is encrypted, because I've already booted the machine up and entered the key. I'm certainly not the most cryptographically knowledge but using LUKS on Oracle Linux, I'd enter the key once while starting up, past that point there was no difference between an encrypted and unencrypted system. It seems logical to me, then, that if something can execute arbitrary code, it's after that point, so encryption won't matter to it. Encryption is more of a solution to someone physically obtaining your hard drive and preventing them from having access to the contents simply by plugging it into their system.

Or at least that's my understanding, please correct me if I'm mistaken.
