The Linux kernel includes the Netfilter subsystem, which is used to manipulate or decide the fate of network traffic headed into or through your server. All modern Linux firewall solutions use this system for packet filtering.
The kernel's packet filtering system would be of little use to administrators without a userspace interface to manage it. This is the purpose of iptables.
You can use "ufw" to configure the firewall.
This is by default disabled.
