IAST: Interactive Application Security Testing in Cybersecurity
IAST stands for Interactive Application Security Testing. Interactive Application Security Testing combines SAST and DAST by instrumenting the application from within during runtime. IAST agents monitor code execution paths, data flows, and library calls while the application handles traffic, producing results with low false-positive rates.
How IAST Is Used in Cybersecurity
Security engineers deploy IAST agents in QA environments to catch vulnerabilities during functional testing without running separate security scans. Security architects evaluate IAST tools for applications where false-positive reduction is a priority. The accuracy of IAST findings speeds up triage when security teams are outnumbered by development teams.
