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 there,

Win10 is soon not supported. Tbh Linux have been on my radar since I started to break from the US big tech.

But how is security handled in Linux? Linux is pretty open-source, or am I not understanding it correctly. So how can I as a new user make sure to have the most secure machine as possible?

Great to hear you're willing to move to Linux!

Like other comments pointed, there is no such thing as "most secure". It's a deep rabbit hole and it's better in general to assume that any device connected to the internet is at risk. Hell, any storage can be compromised if the entity interested put enough effort into it.

I recommande reading the page on Privacy Guides, it gives a good overview. In general, you should consider your thread model: what is you situation and why do you want security or privacy for?

Regarding security, I would say for a general case, any modern, popular Linux distro with full disk encryption is probably good enough and as secure as any other OS. I would recommande going with a Fedora Silverblue or an OpenSUSE Tumbleweed, but the more popular Ubuntu or Mint are great as well for new users.
If you also want "good enough" privacy, you should focus more on the software you are running, and the situation of your data, especially in your usage of your web browser. But that's a different topic entirely.
If you actually want more advanced security though, that's where it becomes difficult/fun. You need to consider what you are trying to protect yourself from, specifically. Virus? Maybe a compartmentized OS like Qubes might be a solution. Physical access to your device? You can get a dead man switch that kills you system disk if your laptop is taken away from you. You want to hide your OS install from a security inspection? You can set a deniable full disk encryption with a facade OS that protect your from a rubber hose attack. Probably many other things exist I am not aware of.

But anyway, if your question is "Is a Linux distro at least as secure as my previous Windows", the answer is definitely YES imo. And if you want MOAR, it's gonna be a fun ride!

[edit: and yes, updates! Update you system plz.]
