To reduce 90% of common post here i decided to learn to use salt on Qubes to provide pre-configured hardened template and browsers. I spend 3-4 days working on this.

What is salt ? Read here https://doc.qubes-os.org/en/latest/user/advanced-topics/salt.html but with simple term you can say it's a "advanced bash script" to setup your own config under Qubes

Once you have installed everything i recommend you to switch to this guide https://forum.qubes-os.org/t/qubes-os-live-mode-dom0-in-ram-non-persistent-boot-ram-wipe-protection-against-forensics-tails-mode-hardening-dom0-root-read-only-paranoid-security/38868

The guide target advanced Qubes users (for now) i will provide the same setup for noob users soon

The guide is using debian-13-minimal and fedora-43-minimal template so you will need to install those templates before starting

The debian/kicksecure salt file require sys-whonix to setup the template but the fedora salt file do not require sys-whonix

To use the "automatic installation" file you need to move the file inside dom0 with this command

qvm-run --pass-io <src-vm> 'cat /path/to/file_in_src_domain' > /path/to/file_name_in_dom0

To be more clear the command must look like this

qvm-run --pass-io fedora-43 'cat /home/user/Downlods/firefox.sls' > firefox.sls

Then do sudo mv (name of the file) /srv/salt/

or you can use this guide to copy paste easily

The file must be put at /srv/salt/(name of the file).sls

The name of the file doesn't matter you can name the file ex.sls it will work

In dom0 open a terminal and do sudo qubesctl state.apply librewolf (don't put "sls" at the end of the command) sudo qubesctl state.apply x where x = the name of the file in /srv/salt/

If you do not have enough ram the installation process will abort so don't open too much vm at the same time.

Features :

✅ Deny read access to root file system , home directories except Downloads and machine-id for browsers using my apparmor profiles ✅ Dark theme enabled by default ✅ Anonymize hostname at boot for Template, Appvm, Dispvm (works only for deb/kicksecure template for now.. the script doesn't work in fedora template i don't know why..) ✅ Every installation of browsers will be done by using apt-transport-tor (for deb based template) because fedora do not provide this feature ✅ Firefox is using arkenfox user.js and brave is hardened by default the browser profile is coming from here no telemetry , no ai enabled etc... ✅ qvm-firewall enabled by default for the Appvm we allow only dns traffic , https , http trafic everything else will be drop ✅ Minimize debian even more thanks to qubist post ✅ Automatically install Ublock origin when firefox start (like librewolf) ✅ Automatically setup wget proxy and curl proxy to install software in the template (works only in debian for unknow reason) ✅ Apparmor enabled by default the browser , Nautilus and qubes features will use my apparmor profiles

I provide only two files because there is more than ~ 3 500 lines for all salt files and if i have to edit the post to update the content it would be painful for me almost impossible

To get the kicksecure version only brave for now go on my repo To get the debian version go on my codeberg repo

To get the fedora version go on my codeberg repo

Technical details information

Every files have the same logic.

  1. Update the original template , shutdown the original template clone the template

  2. Debian and kicksecure files is using the onion repository of Qubes to update the system

  3. To allow users to use tor in brave-browser i added the tcp 9050 ports in the firewall for the brave file

  4. Debian is using the backports repository mixed with the stable repository to get recent packages and fix

  5. Debian andd kicksecure is using the unstable version of apparmor because of this issue

  6. The brave hardened value and arkenfox js profile is fetched from my codeberg repo i didn't touch anything to the original files

  7. Qubist provided a list of packages that can be removed in debian-13 i didn't removed nano , vim perl, gnupg

  8. IMCP request will not work due to the qvm-firewall rules i applied

  9. In debian template i removed xterm in favor of Alacritty terminal

  10. I probably forget some details but you can inspect the salt content if details are missing i will add them later

Know issue :

Missing :

❌ A salt file to automatically update the apparmor profile from my repository to the template (i will do it soon)

❌ I didn't enable selinux for fedora to avoid any problem for users. Fedora-43 seems unstable for now nautilus doesn't launch properly. I replaced nautilus by thunar for fedora ❌ Hostname anonymize feature doesn't work on fedora i will need help for make the script work in fedora

❌ Librewolf is not in dark mode on fedora or debian i forget which one

❌ I'm not really sure if the qvm-features anon-timezone 1 is properly working in my testing i get the same issue as https://forum.qubes-os.org/t/anon-timezone-doesnt-work-for-me/39539 i enabled anon-timezone 1 for every salt file but my timezone didn't change when i tested on website like https://browserleaks.com/

Feel free to contact me on element @aatrfs76519:nope.chat for any suggestion about the guide

The curl and wget proxy The dark theme Brave browser hardened is coming from here To setup arkenfox js and ublock for firefox i used my own guide The qvm-firewall is coming from this discussion
