Four approaches to application security testing, each with different strengths: SAST (Static Application Security Testing) analyses source code for vulnerability patterns — fast but high false positives, misses runtime issues. DAST (Dynamic Application Security Testing) tests running applications from outside — finds real vulnerabilities but limited coverage. IAST (Interactive AST) instruments the application during testing — better accuracy but requires test traffic. Manual Penetration Testing — finds business logic flaws, chained vulnerabilities, and complex attack paths that automated tools fundamentally cannot detect. The optimal approach combines all four, with automated tools for breadth and manual testing for depth.
