About Firewalld
Firewalld was created in 2011 to provide a more flexible and dynamic approach to managing firewall settings on Linux systems. It aimed to replace the older iptables service by offering a more user-friendly interface and the ability to change rules without restarting the firewall. The tool was developed as part of the Fedora project to enhance security management for users.
Firewalld's strengths include its dynamic configuration capabilities, ease of use, and integration with modern Linux distributions. Weaknesses involve a steeper learning curve for those unfamiliar with its concepts and potential performance overhead compared to more lightweight solutions. Competitors include iptables, nftables, and UFW (Uncomplicated Firewall).
