Most of that nasty malware stuff is made to target Windows, so using Linux will give ya a bit of an edge. When you're setting up Linux, make sure to pick the option to encrypt your whole hard drive and use a long-ass passphrase, like 8 to 32 characters, without any recovery passphrase or USB key.
After you've got Linux up and running, the first thing you should do is install and turn on a firewall for better security. On Debian or Debian-based distros, just run these commands:
Code: Select all
sudo apt install ufw
sudo ufw enable
sudo systemctl enable ufw.serviceThat'll get the Uncomplicated Firewall all set up and working, making your system a bit more secure.
If you've got GNOME or KDE as your desktop environment, when you're at the login screen, click on the settings and choose the Wayland windowing protocol. That can stop any Linux malware from snooping on your keystrokes and taking screenshots.
Now, listen up - never download anything straight onto your main computer, always use a virtual machine. Whonix is a good option for that. And you can set up the firewall in your VMs too. Make sure to turn off any file or clipboard sharing between the guest and host, for extra security.
Every day, run these commands to keep your Linux and VMs up to date:
Code: Select all
sudo apt update
sudo apt upgradeAlright, that's the tech stuff sorted. Just use your common sense, yeah? If something sounds too good to be true, it probably is.
