Application Security courses can help you learn secure coding practices, threat modeling, vulnerability assessment, and incident response strategies. You can build skills in risk analysis, secure software development lifecycle (SDLC) integration, and penetration testing techniques. Many courses introduce tools like OWASP ZAP, Burp Suite, and static analysis tools, showing how these resources are used to identify and mitigate security risks in applications.
