Network security courses can help you learn about firewalls, intrusion detection systems, and encryption protocols. You can build skills in risk assessment, incident response, and vulnerability management. Many courses introduce tools like Wireshark for network analysis, Nessus for vulnerability scanning, and various security information and event management (SIEM) systems, showing how these skills are applied in practical work to protect networks from cyber threats.
