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.

Hi. I wanted to know if it's needed to install a firewall on a linux desktop/laptop. Why yes or why no?

Let's just say the system does not have any outward facing service (no ssh, http, smb, nfs).

At that point why not just have the firewall set to deny everything just to be safe though? There's always the chance you missed something that's decided to listen on some random port and if you aren't using anything that listens on a network why have the firewall open anyway
