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?
Its best to have some defence in depth. Ideally you would have a firewall on your network AND your local machine. If you are running a laptop definitely have a local firewall on that as you cannot trust random networks you connect to when out and about in the world.
firewalld is sufficient, i suggest learning its CLI as it is not super complicated. ufw is ok if you are allergic to command line.
