I am not satisfied with Linux’s security and have been researching alternative open source OS for privacy and security So far only thing that’s ready to use is GrapheneOS (Based on Android) but that’s not available on desktop (Though when Android release Desktop mode it may become viable)

Qubes OS is wrapper around underlying operating systems, so it doesn’t really fix for example Linux’s security holes it just kinda sandbox/virtualize them

OpenBSD is more secure than Linux on a base level but lack mitigations and patches that are added to linux overtime and it’s security practices while good for it’s time is outdated now

RedoxOS (Written in Rust) got some nice ideas but sticks to same outdated practices and doesn’t break the wheel too much, and security doesn’t seems to be main focus of OS

Haiku and Serenity are outright worse than Linux, especially Haiku as it’s single user only

Serenity adopted Pledge and Unveil from OpenBSD but otherwise lacks basic security features

All new security paradigms seems to be happening in microkernels and these are the ones that caught my eyes

None of these are ready to be used as daily driver OS but in future (hopefully) it may change

Genode seems to be far ahead of game than everything else

Ironclad Written in ADA

Atmosphere And Mesosphere Open Source Re-implementation of Nintendo Switch’s Horizon OS, I didn’t expected this to be security-oriented but seems like Nintendo has done a very solid job

Then there are Managarm, HelenOS, Theseus but I couldn’t figure out how secure they are

Finally there is Kicksecure from creators of Whonix, Kicksecure is a linux distro that plans to fix Linux’s security problems

if you know of any other OS please share it here

    What kind of threat model makes Linux not secure? (Genuinely curious, I daily drive Fedora and use Flatpaks for sandboxing)

      Any threat model tbh, your linux computer can be remotely used for botnet and you may not even find out (unlikely as linux is not targeted as much as windows simply because too few desktop linux users) Linux desktop’s only advantage currently is obscurity but that may not remain the case with rise of popularity in Steam Deck

        I’m no expert, but I don’t know if I agree with the premise that Linux desktop is secure via obscurity. Linux is probably the largest effort to create a secure OS, and the Linux desktop benefits greatly from that effort.

        OpenBSD has an excellent security track record and is regularly updated, I’m not sure if I believe that its security is “outdated.”

        botnet

        Google has been showing me ‘suspicious activity from your computer’ Captcha lately Is there a way I can scan my device for my peace of mind(not talking about clamAV) a manual inspection, what are the signs that something is wrong?

          No good solution but easiest thing to do is System monitor resource usage (CPU, GPU, Memory) check it when programs are closed and system is idle

          Captcha is probably unrelated to botnet, it can be from your browser (most privacy focused browsers like LibreWolf, Brave, Hardened Firefox get this captcha problem) or your VPN/proxy if you use one

        Linux is the number one priority target for APTs and other threat actors. Linux runs most of the corporate world, therefor its the biggest target.
