Dynamic Application Security Testing (DAST)

Q: What is Dynamic Application Security Testing?

Dynamic AST (DAST) is a security testing method that analyzes running applications from the outside in to identify vulnerabilities by sending crafted inputs and observing responses at runtime without requiring access to source code. Expanded Explanation 1. Technical Function and Core Characteristics Dynamic AST evaluates web or network-accessible applications during execution by interacting with exposed interfaces such as Hypertext Transfer Protocol (HTTP), APIs, and input fields. It detects
