Testing methods

IAST

Interactive Application Security Testing

Interactive Application Security Testing (IAST) uses an in-application agent to observe data flow and code execution while the application is exercised by tests or traffic. By combining runtime visibility with code-level context, IAST can reduce false positives, but it requires deploying an agent and is limited to code paths that are actually exercised.

Key points

  • Agent-based: instruments the app to watch execution during testing.
  • Blends runtime and code context to cut false positives.
  • Only covers code paths that tests or traffic actually reach.

FAQ

How is IAST different from RASP?

IAST is a testing technology that observes an app during testing to find vulnerabilities. RASP is a runtime protection technology that detects and blocks attacks against an app in production. They share instrumentation but serve different goals.
