CompTIA Security+ courses can help you learn network security, risk management, cryptography, and compliance. You can build skills in threat analysis, incident response, and security architecture. Many courses introduce tools like firewalls, intrusion detection systems, and security information and event management (SIEM) software, demonstrating how these tools are used to protect systems and data from cyber threats.
