Firewall courses can help you learn network security principles, configuration techniques, threat detection, and incident response strategies. You can build skills in monitoring traffic patterns, implementing access controls, and analyzing security logs. Many courses introduce tools like Cisco ASA, Palo Alto Networks firewalls, and open-source solutions such as pfSense, demonstrating how these tools are used to protect networks from unauthorized access and cyber threats.
