IAST (Interactive Application Security Testing) – ISTQB Definition
Last Updated: July 12, 2026 · SoftwareTestPilot QA Team
Official ISTQB Definition
A hybrid security testing approach that instruments the running application to observe behavior during functional tests and detect vulnerabilities.
In simple words
A middle ground between SAST and DAST that watches the app from inside as tests run.
Exam tip
IAST tools sit inside the app runtime and correlate code with observed traffic.
