Deny incoming traffic that you don't need by default. For example, if
you don't need to allow incoming traffic for FTP, you can run the following
command:
sudo ufw
deny ftp
6.
Enable ufw by running the following command:
sudo ufw enable
7.
To check the status of ufw, run the following command:
sudo ufw status
This will display a list of rules that ufw is currently

Note: These steps are
just a basic configuration of ufw. You may need to adjust the firewall
settings based on your specific requirements.
