Yes, iptables is there by default. An introduction to iptables is at

https://help.ubuntu.com/community/IptablesHowTo

Depending on your needs, you might find it easier to use a front end to
configure iptables - " firestarter" for example is available in the
universe repository . For information about repositories and installing
software see

https://help.ubuntu.com/community/Repositories

If you don't have any servers installed and running ( sshd, apache etc) you
may not need a firewall, since Ubuntu has no services/daemons listening by
default, so a scan would just show all ports "closed" anyway. If you prefer
to have all ports "Dropped" ( what Steve Gibson of grc.com rather
misleadingly refers to as "stealth" ) , then either straight iptables or
firestarter etc. can do this. For more on iptables try 

firefox file:///usr/share/doc/iptables/html/packet-filtering-HOWTO-1.html
