I see you post a lot about security so I just wanted to chime in and say that maybe just use what works well for you because there’s nothing inherently safe, only stuff that is easier to break and stuff that takes more time. The only real way to be safe is to be prudent with what you download and what you do on the internet.

This is not a very good question. If you are concerned about security you need to think about what specifically you are trying to keep safe? Here are some examples of different security scenarios:

1. Do you want your computer to be safe when it is stolen?
2. Do you want to run lots of native apps from untrusted sources?
3. Do you want it to be used by many people and you don’t want them to be able to steal each others secrets?

Each one of those questions has different means of securing the computer. With question 1, it is not so much a matter of desktop environment, rather it has more to do with using full-disk encryption, setting a boot password in UEFI, and always having your lock screen enabled.

With question 2, this is a much more difficult task and you would probably be better off running apps in a VM, or carefully crafting your “Security Enhanced” Linux profile – or not using Linux at all, but using FreeBSD which allows you to run apps in jails.

With question 3, be more careful with filesystem permissions and access control lists, setup your sudoers file properly, and use a desktop environment with better security auditing like Gnome or KDE Plasma.

Could you provide some criteria for what you’re looking for in the way of security? Wayland is far better for security than Xorg, but it’s hard to say how much it varies between wayland compositors. I can’t imagine it would matter too much, but depending on how much security you’re looking for, choosing more minimal software is probably better. Rust can be better for security but I’m not entirely sure how much can really get compromised through poor memory management in a window manager.

IF by “security” one means bugs have been prevented from living in it, there is one coded in Haskell, it may be named XMonad or something…

( … digging … )

Yep:

https://en.m.wikipedia.org/wiki/Xmonad

from there:

“Due to the small number of lines of code of the Xmonad application, the use of the purely functional programming language Haskell, and recorded use of a rigorous testing procedure it is sometimes used as a baseline application in other research projects. This has included re-implementation of xmonad using the Coq proof assistant,[31] a determination xmonad is an imperative program,[32] and studies of package management relating to the NixOS linux distribution.[33]”

Dig: 2000-ish lines of code.

All else being equal, less code and less dependencies is safer. The bigger the application and the more it tries to do, the larger its attack surface.

(Again, all else being equal. DWM is probably smaller than Weston, but Weston doesn’t let just any old process log keypresses or take screenshots, so probably at least arguable to say that Weston is (qualifier, handwave, condition, clarification) “safer.”)

If you’re going to be that level of paranoid might as well not have graphical interface at all.

As others said, depends on the definition.

I throw Tails into the ring.

Having a non-persistent system makes it safe in some way.

Made in Rust is not synonym of safety. Every code is as safe as its programmer made it be.

You really should press Ctrl+alt+f3 on your lock screen and get your mind blown.
