Updating that as this is not true. You are going to need some sort of firewall as you don't just want to free all your ports to the world, this is also to stop other locals on the network gaining access. You are going to want to configure for example iptables which is default firewall used in linux systems. The easiest way to do this is through the command-line interface terminal. Another firewall you can use (Designed for Ubuntu is UFW).

Also, you are going to want to read up on SSH security as it's not just viruses you want to worry about. Infact don't worry about viruses at all. Viruses on Linux systems are theoretically possible but very few actually exist, and you should read further when following tutorials and make sure they don't tell you to wget some random thing. Something like IDS for extra security which is a Network Intrusion Detection System, this can help if you are running a dedicated server and someone locally or even externally are trying to break into your system through the traffic.
