Will this be enough security for a Ubuntu machine?

[LukeLovesSecurity]

I was thinking of just using GUFW, a hardened browser, NordVPN, and NordVPN's DNS. Will this be enough to secure my Ubuntu machine? Should I add something?

Should I add something?

I think, none. You're pretty much covered

Seems covered by me! uBlockOrigin works on Linux too I believe. This may be a bit overkill though. HTTPS works inside Ubuntu too! Again, this may be a bit overkill too.

Added stuff (may not be needed)

Sophos: Free Linux Malware Scanner | Lightweight Agent for Linux Malware Detection and Removal | Sophos AV Tools

Comodo: Antivirus for Linux | Free Linux Antivirus for Virus Protection

My ElementaryOS partition is equipped with Chromium browser (HTTPS Everywhere, NoScript, uBlock Origin, Norton Safe Web), VPN and Comodo DNS. The rest is knowledge on browsing and basic security. Do not install or give sudo permissions to anything you do not know what it is. Stick to the store's software or be sure what you're installing.

On linux , I used extensions for security purpose. Like RoboMan saidm be sure what you installing on Ubuntu.

If it is enough, not giving the password to unknown programs and keeping the system updated is enough.

If you are paranoid, use AppArmor

If you are paranoid, use AppArmor

I checked it out, but it seems like a lot of work to set up. Besides, I struggle downloading a program, I don't think I'll be using app armor any time soon.

There is Security-Enhanced Linux (SELinux), but it's pretty advanced stuff and likely overkill for normal use.

Official wiki.

That should be a perfectly fine setup as long as you follow simple rules such as only installing from trusted sources (such as the official repositories).
