Securing Ubuntu: Use UFW Firewall

A lot of you probably already know this, then again some of you might not of thought about it too much. I mean, you're using Linux right? Nobody is going to be able to hack it right? Not necessarily.

I got to thinking about this because I use Ubuntu exclusively for work and for home, and the other day I was working remotely from a coffee shop in Grand Junction Colorado. I had just recently re-built my laptop with Ubuntu and hadn't installed a firewall yet. Mainly because I usually work from home and I'm behind an appliance firewall there.

So anyway, not wanting to be hacked by some guy in a coffee shop I installed my favorite firewall for Ubuntu, gufw. It is the gui front end to the ufw firewall.

To install it is easy, just run:

sudo apt-get update && sudo apt-get install gufw
Once installed setup is super easy. Just turning it on will block all incoming connections and allow all outbound connections.

Having that installed and running, especially in a place with shared wifi, it makes me feel a little bit better.

Do you use a different firewall in Ubuntu? Which one do you use? Let us know in the comments!
