Ubuntu does not come with a built-in firewall by default, but there are a number of firewalls available for installation. A few popular firewalls for Ubuntu are: ufw, iptables, and netfilter-persistent.

Some people argue that a firewall is not necessary on a Linux system, as the operating system’s security features are adequate. However, a firewall can help to protect your computer from unauthorized access, as well as protect yourself from malicious software that may be attacking your computer.

In addition, a firewall can also help to protect your data from being stolen by hackers.

Overall, it is up to the individual user to decide whether or not they feel a firewall is necessary on their Ubuntu system. However, it is generally recommended that users install a firewall to help protect their computer.
