What is DAST in Cybersecurity?
Dynamic Application Security Testing probes running applications for vulnerabilities by sending crafted requests and analyzing responses. DAST tools operate as external attackers, testing for injection flaws, authentication weaknesses, and configuration errors without access to source code. They find runtime issues SAST cannot detect.
Why DAST Matters for Your Cybersecurity Career
DAST validates whether vulnerabilities are actually exploitable in a running environment. Penetration testers use DAST tools as part of web application assessments. Security engineers schedule automated DAST scans against staging environments before production deployments. DAST complements SAST by catching server configuration and runtime-specific vulnerabilities.
