Managing Dependency Vulnerabilities in Web Applications

Modern web applications rely heavily on open-source packages, but outdated or insecure dependencies can expose your software to critical security risks. This text-based course provides a clear, foundational guide to identifying, analyzing, and mitigating known vulnerabilities in your project's dependency tree. Through structured written explanations and practical code examples, you will transition from manually managing packages to implementing automated security workflows. You will learn to evaluate the severity of reported vulnerabilities and apply appropriate fixes without breaking your application's functionality. What you'll learn: - Understand the fundamentals of Software Bill of Materials (SBOM) and dependency risk management - Identify known security flaws using scanning tools like npm audit and automated security alerts - Evaluate vulnerability severity levels using standard security scoring systems - Resolve security issues safely through package updates, patches, and lockfile overrides - Configure automated dependency update tools to proactively maintain package health - Integrate basic dependency scanning into modern development workflows The course begins with essential security terminology and core concepts before guiding you through hands-on scanning techniques and remediation strategies. You will read real-world scenarios, examine package configurations, and practice resolving dependency conflicts through written exercises. This course is designed for beginner web developers, junior software engineers, and technology creators who want to build secure applications from the start. No prior experience with application security is required. Start building safer web applications today by mastering dependency security.
