Definition
Interactive application security testing (IAST) is a method of examining a web application’s behavior to detect security vulnerabilities during runtime.
It combines aspects of static application security testing (SAST) and dynamic application security testing (DAST) to provide comprehensive security testing within the application.
IAST Examples
- Continuous integration/continuous deployment (CI/CD): IAST is included in the CI/CD infrastructure to provide continuous security feedback.
- Web application development: IAST can be implemented in the software development cycle to detect and correct potential security threats in real-time.
IAST Pros
- High precision: IAST minimizes false positives by analyzing applications during runtime.
- Real-time feedback: IAST offers real-time results, allowing developers to address vulnerabilities quickly.
IAST Cons
- Possible performance impact: Although IAST provides real-time insights, its implementation and operation can affect the application’s performance.
- Complex integration: IAST’s integration is more complex than SAST or DAST.
Using IAST
- Incorporate IAST in your DevSecOps strategy to maintain continuous security throughout development.
- Use IAST with DAST and SAST for a multi-layered, solid security testing framework.
