Every Linux Distro ships with an active ip filter (also called personal firewall) known as iptables.
Ufw and it's graphical gufw are just simpler user interfaces for iptables.
By default all ports are closed if you not start an application which opens up a port (ssh server or Webserver, smb server and so on)
