Interactive Application Security Testing (IAST)

Interactive Application Security Testing (IAST) is a dynamic application security testing methodology that combines elements of both Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST). IAST assesses the security of running web applications by monitoring and analyzing code execution during runtime. It provides real-time insights into security vulnerabilities and weaknesses, making it a valuable tool for enhancing DevOps and DevSecOps processes. Let's explore how IAST enhances DevOps and DevSecOps and examine various IAST solutions, technologies, and their references.

How IAST Enhances DevOps and DevSecOps:

1. Shift-Left Security: IAST aligns with the "shift-left" approach by integrating security testing early in the software development lifecycle. It enables developers to identify and remediate vulnerabilities during the development phase.

2. Continuous Testing: IAST can be integrated into Continuous Integration/Continuous Deployment (CI/CD) pipelines, allowing for automated and continuous security testing as code changes are made. This ensures that security remains a focal point throughout the development process.

3. Real-Time Analysis: IAST provides real-time insights into code execution and security vulnerabilities as applications run. This enables developers to address issues as they arise, reducing the time-to-fix vulnerabilities.

4. Reduced False Positives: IAST typically generates fewer false positives compared to traditional scanning tools, leading to more accurate vulnerability findings and faster remediation.

5. Rapid Feedback: By offering feedback during runtime, IAST helps developers understand how their code interacts with security vulnerabilities and provides guidance on how to fix issues effectively.

Different IAST Solutions and Technologies:

1. Contrast Security: Contrast Security offers IAST solutions that provide runtime application protection, vulnerability detection, and attack visibility. It supports various programming languages and integrates with CI/CD pipelines.

2. Checkmarx Codebashing: Checkmarx Codebashing combines IAST with interactive training. It identifies vulnerabilities during runtime and provides developers with immediate guidance on fixing security issues.

3. HCL AppScan: HCL AppScan offers IAST capabilities that help organizations identify vulnerabilities in running applications and APIs. It integrates with DevOps pipelines for continuous testing.

4. Qualys WAS with IAST: Qualys Web Application Scanning (WAS) includes IAST features, offering continuous monitoring and real-time vulnerability detection in web applications.

5. TCell by Rapid7: TCell, now part of Rapid7, provides runtime application self-protection (RASP) with IAST capabilities. It detects and protects against runtime attacks while identifying vulnerabilities.

How IAST Benefits Application Security:

• Real-Time Vulnerability Detection: IAST identifies security vulnerabilities during runtime, enabling organizations to detect issues that may only manifest under specific conditions.

• Accuracy: IAST typically produces fewer false positives compared to traditional static analysis tools, reducing the burden on development teams and ensuring that they focus on real security risks.

• DevSecOps Integration: IAST seamlessly integrates with DevOps and DevSecOps pipelines, allowing organizations to automate security testing and provide immediate feedback to developers.

• Continuous Monitoring: IAST offers continuous monitoring of applications, ensuring that new vulnerabilities introduced with code changes are promptly identified and mitigated.

• Remediation Guidance: IAST provides actionable remediation guidance, assisting developers in understanding and fixing security vulnerabilities effectively.

• Runtime Protection: In addition to detection, some IAST solutions offer runtime protection capabilities, actively defending applications against attacks.

Interactive Application Security Testing (IAST) is a valuable tool for enhancing application security in DevOps and DevSecOps practices. By integrating IAST into CI/CD pipelines and utilizing robust IAST solutions and technologies, organizations can identify and remediate security vulnerabilities in real-time, reducing the risk of exploitation and enhancing the overall security posture of their applications.
