About this course

Building secure software requires understanding how attackers exploit weaknesses. This course teaches you to identify critical security flaws in Java applications from both an offensive and defensive perspective. By studying real-world vulnerability patterns, you will transition from writing functional code to writing secure, resilient Java code. You will understand how security breaches happen, how to exploit them in a controlled environment, and exactly how to refactor your codebase to eliminate these risks entirely. What you'll learn: - Understand foundational application security concepts and the common vulnerability landscapes. - Exploit and patch injection vulnerabilities, including SQL injection and command injection. - Defend against Cross-Site Scripting (XSS) and broken authentication mechanisms. - Analyze and secure third-party dependencies using modern software composition analysis (SCA) principles. - Implement secure coding practices using modern Java features and robust security configurations. The course begins with essential security terminology and foundational concepts before guiding you through hands-on, text-based scenarios where you analyze vulnerable Java code, understand the exploit vector, and apply the correct secure coding patches. This course is designed for beginner developers, software engineers, and security enthusiasts who want to build a strong foundation in Java security without needing prior application security experience. Start reading to master the fundamentals of secure Java development and protect your applications from modern threats.

Learned a good amount here. The examples were relevant, though I wished there were a few more practical application tasks. Still, a worthwhile experience.
