Hi
I was wondering how do I enable AppAmor to gain some extra security, I tried a couple of months ago but I never managed to do so ? I would appreciate some tips and tricks.
Do you know this site? https://wiki.archlinux.org/title/AppArmor
What @Omig said. Pretty much anything you’d like to learn is on the Arch Wiki. If you have already read it and couldn’t understand it, that’s where we come in. 
Based on what I remember reading just about 2 weeks ago is that if you want to use AppArmor or SELinux, it’s better to use a distro that enables it from the start. It’s not straight-forward on Arch distros.
Ok yes that’s pretty unfortunate because I really like Endeavor OS but I do need and care about security.
You could install a distro that uses AppArmor or SELinux, then use EndeavourOS/Arch through Distrobox. That way, your base system is secure in the way you want, while still getting access to the latest packages.
I did this using the instruction from the link posted before.
sudo pacman -S apparmor
sudo systemctl enable apparmor
sudo systemctl start apparmor
You need to add kernel parameters:
lsm=landlock,lockdown,yama,integrity,apparmor,bpf
I use Grub so I added these to /etc/default/grub in the line GRUB_CMDLINE_LINUX_DEFAULT
and then ran: sudo grub-mkconfig -o /boot/grub/grub.cfg
If you use systemd-boot, the instructions are in EndeavourOS Wiki:
https://discovery.endeavouros.com/installation/systemd-boot/2022/12/
I don’t know if this is all you need to do.
When I check:
$ aa-enabled
Yes
$ sudo aa-status

Well this certainly seems simple enough, and rereading the AppArmor wiki, also seems simple. So, I guess I read the SELInux wiki and thought they were both complicated, because SELinux has a bunch of AUR packages that you need to use it effectively.
Hi sorry my late reply I have been out of town, but I will try taking a look at this explain and install. I also saved the Arch wiki that is gold to have all that info
Hi I tried to install appamor and make it work, but for some reason I could not make it work, man its a pain on arch based linux distros
