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?
Unless you mess around with firewall commands/settings you don't understand firewalld should be sufficient.
That being said you might have to allow certain services at some point (openvpn) for example
