Hey 👋 dear Linux Community,
(infosec.exchange)
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.

As other have mentioned, setting up Timeshift + a firewall is a good start. I'm 99% sure that LM guides you through both of these processes on first boot, but it's a good thing to check on anyways. LM is pretty sanely put together out of the box, so I'd honestly just recommend you use it as-is and tweak things when/if you run into something that isn't doing it for you.
Other than that, welcome to the party!
