Interactive Application Security Testing (IAST) Glossary Definition

Interactive Application Security Testing (IAST) analyzes an application while it runs, often using instrumentation to observe code paths, data flow, and vulnerabilities.

Interactive Application Security Testing (IAST) is a DevOps security concept that integrates security, compliance, and risk controls into software delivery and operational workflows.

IAST can combine runtime context with code-level insight during testing.

Security, development, and operations teams use this concept to make security checks continuous instead of treating them as a late-stage review.

Related concepts include DevOps, DevSecOps, Security Automation and Software Supply Chain.
