The need for effective and efficient security testing has surged as applications become more complex, with Interactive Application Security Testing (IAST) emerging as a solution that monitors applications in real-time to spot vulnerabilities before they can be exploited. IAST is perfectly fit into the integrated ethos of DevSecOps, merging development, security, and operations. The core concepts of DevSecOps emphasize prioritizing security from day one, ensuring collective accountability among developers, operations, and security teams, and always-on security monitoring. By integrating IAST into DevSecOps, developers can gain instant feedback, fewer false alarms, early issue spotting, smooth compliance, and empowered developers. However, proper tool selection, data management, and team training are critical components to nail, as New Relic IAST is designed for developers, providing real-time, actionable insights that align seamlessly with DevSecOps.
