What is Dynamic Application Security Testing in Cybersecurity?
A testing platform that probes running web applications and APIs from the outside by sending crafted requests to discover vulnerabilities like injection flaws, authentication bypasses, and configuration errors. DAST requires no access to source code, testing the application as an attacker would. Modern DAST platforms support REST and GraphQL APIs, single-page applications, and authenticated scanning.
Why Dynamic Application Security Testing Matters for Your Cybersecurity Career
DAST finds vulnerabilities that static analysis misses because it tests actual runtime behavior. Security engineers integrate DAST into CI/CD pipelines and pre-production testing. Penetration testers use DAST tools as part of their testing methodology. Understanding the strengths and limitations of DAST versus SAST and IAST is a core application security competency.
