Codebase Security Analysis with CodeQL for Beginners

Security issues in code can lead to devastating breaches if they are not caught early in the development lifecycle. This text-only course guides you through using CodeQL, the powerful semantic analysis engine, to discover critical vulnerabilities before they ever reach production. You will gain a solid foundation in static application security testing (SAST), learning how to treat code as data to identify deep-seated security flaws. What you'll learn: - Understand the foundational concepts of semantic code analysis and CodeQL database structures. - Run standard security queries to detect common vulnerabilities like SQL injection and cross-site scripting. - Write custom CodeQL queries to enforce specific security policies and modern coding standards. - Integrate automated security scanning into CI/CD pipelines for continuous repository monitoring. - Analyze scan results to triage alerts, minimize false positives, and implement secure code fixes. Starting with key security terminology and foundational definitions, this course builds your knowledge step-by-step. You will move from understanding basic relational program analysis to writing your own custom queries and automating repository scans. This course is designed for beginner developers, security enthusiasts, and DevOps engineers with no prior experience in static analysis. Start securing your applications from the inside out today.
