Linux security courses can help you learn system hardening, user access controls, network security protocols, and incident response strategies. You can build skills in configuring firewalls, implementing encryption techniques, and conducting security audits. Many courses introduce tools like iptables for firewall management, OpenSSL for encryption, and Wireshark for network analysis, showing how these skills are applied in practical work to protect systems from vulnerabilities and threats.
