Information security courses can help you learn risk assessment, network security protocols, encryption techniques, and incident response strategies. You can build skills in threat analysis, vulnerability management, and compliance with security regulations. Many courses introduce tools like firewalls, intrusion detection systems, and security information and event management (SIEM) software, demonstrating how these tools are applied to protect data and maintain system integrity.
