Do I need a firewall for my fedora 38?
I’m new to Linux, previously been on Windows where I used defender + Windows firewall. Now I’m on fedora which also have its firewall called firewalld. Are those sufficient, or do I need any other solutions for my security?
Fedora doesn’t use AppArmor, it uses SELinux.
You normally only use SELinux or AppArmor, not both, since they are the same goal and purpose.
I would definitely keep firewalld and SELinux installed and enabled on any system unless there’s a good reason not to.
