Measuring IAST Effectiveness

Detection accuracy metrics validate IAST's low false positive claims. Track the percentage of IAST findings confirmed as true vulnerabilities. Compare with SAST and DAST false positive rates. Monitor developer feedback on finding quality. High accuracy rates justify the investment in IAST technology and build developer trust.

Coverage metrics ensure IAST analyzes security-critical code. Monitor which application components receive IAST coverage during testing. Track code execution percentages during test runs. Identify gaps where additional testing might be needed. These metrics guide test enhancement efforts to maximize IAST value.

Time to remediation often improves dramatically with IAST due to detailed vulnerability information. Track how quickly developers fix IAST-identified issues versus those from other sources. Measure the reduction in back-and-forth between security and development teams. These efficiency gains often justify IAST investment beyond pure security benefits.
