Dynamic Application Security Testing (DAST) Explained: How Runtime Security Testing Works
Dynamic Application Security Testing (DAST) analyzes applications while they’re running, simulating real-world attacks to uncover vulnerabilities that only appear in production-like environments. In this video, we break down how DAST works, why it matters, and how it complements SAST and IAST in a complete AppSec strategy.
You’ll learn how DAST tools probe applications from the outside—much like an attacker would—revealing issues caused by misconfigurations, deployment environments, integrations, and business logic. We also examine the key differences between DAST and SAST, and how combining both leads to stronger security coverage.
What You’ll Learn
• What DAST is and how it works
• Runtime vulnerabilities and misconfigurations
• How DAST simulates real attacker behavior
• Key benefits and limitations
• DAST vs SAST
• How DAST fits into a modern AppSec program
