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.

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.

@Caaaaarrrrlll @moist_towelettes you mean by default. Everything in Linux can be changed, so if you like AppArmor, you can use it.
