When there is a security breach attempt or anomalous traffic in the network, it detects it automatically and warns network administrators.
Firewalls are often used to protect home networks from external network dangers such as the Internet. They can prevent unauthorized access to sensitive information and the management of network equipment. UFW does not have a specific command for listing rules, but instead utilizes its primary command, ufw status, to provide an overview of the firewall as well as a list of rules.
Your firewall should now be configured to allow SSH connections. To verify which rules were added so far, even when the firewall is still disabled, you can use:
Sudo ufw show added
Output
