Hacking courses can help you learn network security, penetration testing, ethical hacking techniques, and vulnerability assessment. You can build skills in threat analysis, incident response, and secure coding practices. Many courses introduce tools like Metasploit, Wireshark, and Burp Suite, that support testing and securing systems against potential attacks.
