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?

Even without any firewall you should be fine by default. Access to ports with no services listening do nothing. Firewalls are just defense-in-depth in case a service that you didn't want to accidentally listens on a port. It may also slightly reduce kernel attack surface.

So I would say that you don't need it. You will be fine. But if you want to be sure about what is listening on your machine then feel free to apply one.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
