I picked up my new computer and now have linux installed.
My first security measure was to encrypted the home folder and setup a new user account to run bitcoin core. What other security measures do I need to implement?

Will do. Thank you.
Yes, good point, Mullvad VPN. I would install the software and make sure to use the "kill switch" and "lockdown mode" options in the settings to make sure nothing leaves the computer without going through the VPN. I would also suggest using its multihop setting so you can choose different entry and exit servers.
Here are some privacy friendly browsers :
Brave
Librewolf
Tor Browser
Mullvad Browser
It really depends on what you're planning to do with the computer. How versatile do you need it to be, are you planning to generate keys with that computer, for how much money, etc. Depending on that, what you need to do will change.
However, usually, no matter what, I would choose full-disk encryption (during the installation, not only the home folder).
Afterwards, I would make sure it's up to date.
On ubuntu and related distros :
sudo apt update
sudo apt upgrade
Then I would check to make sure I don't have open ports that I don't use. For example, if you won't be printing, you don't need "cups". You can look at which ports are open with :
sudo netstat -lntp
Those are some pretty basic but important steps.
For anything major in the bitcoin world, you can either choose to use in combination with a hardware wallet or go with a disposable computer that will never go online and use it only with a live-dvd linux distribution.
OK. Thank you. I'll start over and re-install Linux with full disk encryption.
