Interactive Application Security Testing (IAST) is a type of application security testing that combines aspects of both static application security testing (SAST) and dynamic application security testing (DAST).
IAST works by deploying a security testing tool within the application itself to actively monitor and analyze the application’s behavior during runtime. This allows IAST to detect vulnerabilities and security issues in real-time as the application is running, providing more accurate and actionable results
Why Use IAST as a Security Testing Method?
1. Comprehensive coverage:
IAST can provide a more comprehensive coverage compared to other testing methods such as DAST or SAST. It can detect a wide range of vulnerabilities including injection attacks, cross-site scripting, SQL injections, and more.
2. Real-time feedback:
IAST can provide real-time feedback during the testing process, allowing developers to identify and fix vulnerabilities immediately as they appear in the code.
3. Accurate results:
IAST can accurately pinpoint the exact location of vulnerabilities within the code, making it easier for developers to fix them quickly and efficiently.
4. Integration with the SDLC:
IAST can be easily integrated into the software development lifecycle (SDLC), allowing security testing to be conducted early and continuously throughout the development process.
5. Reduced false positives:
IAST tends to produce fewer false positives compared to other testing methods, making it more efficient for developers to prioritize and address real security issues.
6. Efficiency:
IAST can help save time and resources by automating the security testing process and providing immediate feedback, reducing the need for manual testing and rework.
7. Compliance requirements:
IAST can help organizations meet regulatory compliance requirements by ensuring that their applications are secure and free from vulnerabilities

How IAST Helps Identify and Fix Security Vulnerabilities
IAST (Interactive Application Security Testing) helps identify and fix security vulnerabilities in a more efficient and proactive manner compared to traditional methods. Here are ways IAST helps in this process:
1. Real-time monitoring:
IAST tools run in the background while the application is being tested, continuously monitoring it for security vulnerabilities. This real-time monitoring allows for vulnerabilities to be detected as soon as they occur, helping to identify and fix them faster.
2. Accurate and actionable results:
IAST tools provide accurate and actionable results by pinpointing the exact line of code where a vulnerability exists. This enables developers to quickly identify and fix the issue without having to sift through a large amount of code.
3. Integration with the development process:
IAST tools can be integrated into the development process, allowing vulnerabilities to be detected and fixed early on in the development lifecycle. This helps prevent security issues from making their way into production.
4. Reduced false positives:
IAST tools use dynamic testing techniques to interact with the application like a real user would, reducing false positives compared to other testing methods. This helps developers focus on fixing legitimate vulnerabilities rather than wasting time on false alarms.
5. Comprehensive coverage:
IAST tools can provide comprehensive coverage by testing the application from different angles and identifying vulnerabilities that may be missed by other testing methods. This helps ensure that all potential security issues are addressed.
