About this course

Every software professional needs a solid grasp of how data is stored and how to protect it from malicious attacks. This course bridges the gap between database management and application security, providing the dual-skill set required in the modern tech landscape. You will develop the ability to interact with databases confidently and adopt a penetration tester's mindset to find and fix security holes in web applications. By following written explanations and code-based exercises, you will transform from a beginner into a developer who understands both the data layer and the security layer of an application. What you'll learn: - Understand foundational database structures and core SQL terminology. - Write complex queries using logical operators, joins, and subqueries to extract and manipulate data. - Manage data integrity through schema design, constraints, and the use of views. - Identify common web vulnerabilities including Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF). - Practice session management security, cookie handling, and parameter tampering detection. - Apply modern security principles such as Zero Trust concepts and updated credential management standards. The course begins with the basics of MySQL syntax and database design before transitioning into offensive security techniques and defensive best practices. You will progress from simple data retrieval to investigating complex security flaws within a web environment. This course is designed for absolute beginners, aspiring software engineers, and quality assurance testers. No prior experience with databases or security testing is required. Begin your journey into data management and web security today.

Found this course to be quite beneficial. The way topics were introduced was effective. Just a minor point, some examples felt a bit dated.
