If you have a Internet facing system, then turn on the firewall.  This 
should *always* be done.  No matter how secure a default install is, it 
is way too easy to unknowingly install a package that listens for 
incoming network connections.

By default, Ubuntu installs UFW.  Basic firewall protection is as simple 
as editing your /etc/ufw.conf file and changing Enabled to yes.
