You can setup a secure basic firewall using the "Uncomplicated Firewall or UFW".

sudo slapt-get -i gufw

then sudo gufw, click status to "on". This will setup a deny all incoming and allow all outgoing firewall.

Alternatively, you can sudo slapt-get -i ufw

then sudo ufw enable

sudo ufw default deny

sudo ufw deny ssh

This method will deny all incoming connections and allow outgoing but also deny ssh connections to further protect your system.

Note: if you require ssh connections then of course do not block it, if you are not sure what ssh (Secure Shell) is, then block it as it will make the system more secure.

For both methods make sure you copy and paste the following to: sudo /etc/rc.d/rc.local, this will allow the firewall to start with each boot.

if [ -x /lib/ufw/ufw-init ]; then

/lib/ufw/ufw-init start
