I've recently started transitioning from Windows to Linux, specifically using SteamOS on my SteamDeck, and I want to ensure I'm keeping my new system secure. I've heard a lot of opinions suggesting that Linux has fewer issues with malware, but I'm not entirely convinced. I know the basics of Windows security like avoiding unscanned .exe files and keeping antivirus software active, but what are the specific steps I should take to maintain good cyber hygiene on Linux? For example, what should I watch out for when installing software, and how can I manage root privileges safely? Any advice on keeping my system secure would be greatly appreciated!

Just like with any OS, use common sense! Don't install software from shady sources and primarily use your distro's package manager. Also, never run commands from unknown origins and avoid reusing passwords—consider using a password manager to help you out. Remember, the user is always the weak link in security!
Linux is designed to be safe, but there are still things to watch out for. Always understand what a command does before running it with sudo, and keep your software updated. Use your package manager for installations instead of downloading random executables from the internet. And remember, just like on Windows, not everything in your distro’s repo is necessarily safe.
Absolutely! Avoiding commands you don’t understand is critical. The manual pages (man) are super helpful too!
Some basics would be to utilize tools like UFW for a firewall and make sure to update your OS regularly. Avoid running as root unless necessary, and instead use sudo for elevated privileges. Implementing AppArmor can help keep your applications in check too. It’s also smart to periodically scan your system with software like ClamAV, though malware on Linux is less common than on other platforms.
To keep your Linux system secure, there are a few guidelines you should follow: Always stick to software from official repositories or trusted sources like Flathub. Avoid adding third-party repos unless you're certain they're safe. Also, never run binaries or scripts from the internet without knowing what they do. Some users might think that Linux is immune to malware, but that's not true—malware does exist. So be careful with addons and plugins, too!
Totally agree! It's always better to check the reputation of any third-party repos before diving in. Flathub is helpful, but it doesn't vet code. Just be cautious, and you’ll be safer.
For sure! I think many new users underestimate the risks. Sticking to official and well-known sources is key.
Lastly, ensure you back up your data regularly with a 3-2-1 strategy. That's three copies of your data, on two different types of media, with one off-site. Also, make sure you understand your system well enough to reinstall if something goes wrong. That way, if all else fails, you can recover easily!
Great point! A solid backup strategy is essential. You never know when something might go wrong.
Exactly! Understanding how to reimage your OS can save a ton of headaches later.
Good tips! I personally run commands in a VM first to see what they do before trying them on my main system.
