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.

Of course, I'm paranoid and don't trust the US government. Or any government really. "First they came for _____" and all that; Id rather just tell them to pound sand immediately instead of get caught with my pants down.

I encrypt my workstations and backups thereof on external devices. To protect against theft or a lazy state-level adversary

I have no significant private data on my disks. They can be wiped whether encrypted or not if they're stolen. And I like that in theory if my pc explodes I can recover the data with only the drive.

[-] netvor@lemmy.world 1 points 4 days ago

I do, laptops and workstations.

It's just too easy not to, and there's almost no downsides to it. (I only need to reboot, once a month or two.)

Well, unless you consider the possibility of forgetting the password a downside, so for that reason I keep the password in a password manager.

In case my laptop was stolen, there would quite a couple fewer things to worry about. Especially things like client's data which could be under NDA's, etc...

are you guys using the bios ssd encryption option or a software solution?

Yes. Encrypting your entire hard drive has basically been a tickbox in the Fedora installer for a long time now. No reason why I wouldn't do it. It's, easy, doesn't give me any problems and improves my devices security with defence-in-depth. No brainer.

It’s a smidge more difficult on Debian if you want to use a non-ext4 filesystem - granted for most people, ext4’s probably still fine. I use it on my desktop, which doesn’t have encryption.

[-] ilickfrogs@lemmy.world 2 points 5 days ago

I encrypt my desktop and laptop but not my servers. On desktop, that excludes drives that aren't my OS/boot drive.

[-] ocean@lemmy.selfhostcat.com 2 points 5 days ago

I encrypt my laptop and desktops and I think it’s worth it. I regret encrypting my servers because they need passwords to turn on. I couldn’t figure out how to handle it when away.

I don't do it for my desktop because 1) I highly doubt my desktop would get stolen. 2) I installed Linux before I was aware of encryption, and don't have any desire to do a reinstall on my desktop at this time.

For my laptop, yes, I do (with exception of the boot partition), since it would be trivial to steal and this is a more recent install. I use clevis to auto-unlock the drive by getting keys from the TPM. I need to better protect myself against evil maids, though - luckily according to the Arch Wiki Clevis supports PCR registers.

[-] Laitinlok@lemmy.laitinlok.com 2 points 5 days ago

Yes because my distro also have encrypted /boot included

[-] potentiallynotfelix@lemmy.fish 2 points 5 days ago

Mostly I don't, but I want to start to. I only have one laptop encrypted and of course I keep my phones encrypted.

[-] boredsquirrel@slrpnk.net 2 points 5 days ago

Yes because it is one click

If I delete my drive, it is rubbish

It doesnt impact my performance much

[-] 9488fcea02a9@sh.itjust.works 1 points 5 days ago

All my important files are on a NAS, so if someone steals my laptop, there's nothing of value there without being able to log in and mount the remote file systems

I don’t have FDE (BitLocker) enabled on my Windows 11 gaming PC. It sits in my house and has nothing on it but video games and video game related shit. I don’t even have my password manager installed for logging in to Steam, GoG or whatever other launcher. I manually type passwords in from the vault on my phone if the app doesn’t support QR code login like discord. Also I paid for this ridiculous m.2 nvme drive, I’m not going to just give up iops bc i want my game install files encrypted.

I don’t use FDE on my NAS. Again it doesn’t leave my house. I probably should I guess, bc there is some stuff on there that would cause me to have industry certs revoked if they leaked, but idk I don’t. Everything irreplaceable is backed up off site, but the down time it would take to rebuild my pirated media libraries from scratch vs just swapping disks and rebuilding has me leery.

I have FDE enabled on both my MacBooks. They leave the house with me, it seems to make sense.

I don’t use FDE on Linux VMs I create on the MacBooks, the disk is already encrypted.

My iphone doesn’t have the option to not use FDE I don’t think.

I use encrypted rsync backups to store NAS stuff in the cloud. I use a PGP key on my yubikey to further encrypt specific files on my MacBooks as required beyond the general FDE.

I encrypt my home folder and Windows install just in case someone breaks into my house and steals my computer. Super annoying entering my password each boot though.

[-] JubilantJaguar@lemmy.world 2 points 5 days ago

Absolutely. LUKS full disk encryption. Comes as an opt-in checkbox on Ubuntu, for example.

And I too cannot understand why this is not opt-out rather than opt-in. Apparently we've decided that only normies on corporate spyware OSs need security, and we don't.

I don't, I didn't do it back then and I ended up using this system for much longer than I thought I would(4+ years). I want to do it next time but I don't feel like reinstalling just for that.

Only encrypt the home partition, for the root partition it just unnecessarily slows down the system.

Also, I think, there could be different approaches instead of encryption. AFAIK, android doesn't use encryption underneath, but uses a semi-closed bootloader (which means, if you install a different OS, all user data gets wiped). I'm currently investigating the feasibility of such an approach in the long term.

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.
