Web Data Security Fundamentals for Developers

In an era of frequent data breaches, securing user information is no longer optional for web developers—it is a core responsibility. Building functional applications is only half the battle; you must also know how to defend them from malicious actors. This course guides you through the foundational concepts of web data security, transforming you from a novice coder into a security-conscious developer. You will learn how to identify common vulnerabilities, implement secure coding practices, and protect sensitive data at rest and in transit. What you'll learn: - Understand foundational security terminology, including encryption, hashing, and the CIA triad. - Identify and mitigate common web vulnerabilities, such as SQL injection and Cross-Site Scripting (XSS). - Implement secure modern authentication and authorization patterns, including token-based auth basics. - Protect sensitive data using modern encryption standards and secure storage practices for passwords and API keys. - Apply zero-trust principles and secure configuration management to prevent unauthorized data exposure. The course begins with essential terminology and security mindsets before moving into practical code examples and architectural patterns. You will read clear explanations, analyze secure code snippets, and complete written exercises to reinforce your learning. This text-only course is designed specifically for beginner web developers and software students who want to build a strong foundation in security without needing advanced prior knowledge.
