Fedora is security? I mean, don't get me wrong, I love it, it's my daily driver after trying just about every distro under the sun, but I would've figured something like Qubes would stand head and shoulders above it.
Fedora has firewalld by default but in the desktop version all ports are open by default. Pretty sure the server version only has ssh and cockpit exposed by default
I haven't looked around that much in years beyond NixOS, what else has MAC by default these days? I remember a lot of the Debian based ones having some things constrained by AppArmor, but I personally prefer SELinux and it wasn't everything.
I don't know if it ships with a firewall, but that's definitely easier than an ad hoc SELinux setup. I always just transfer my iptables (nftables now) rules over.
Yea, but there are also some things AppArmor just can't do. Although in my experience most aren't as big of a deal. Things like saying "only processes of this type can bind to port X" for example and much more fine grained control of file or directory actions. Does AppArmor provide kernel module controls?
I mean, image based (immutable) distros are quite a bit more secure than regular ones, and Fedora Atomic (Silverblue, Bazzite, etc.) is pretty much the only great choice when it comes to those kind of operating systems.
