A DAST tool is a software application that scans the web application and identifies vulnerabilities in a running environment. Unlike SAST tool, which examines the source code, the DAST tool performs black-box testing to identify critical vulnerabilities like SQL injection, XSS, CSRF, and security misconfigurations by simulating real-world attacks.

What are some of the best DAST tools available?

Some of the best DAST tools available in the market are: ZeroThreat, Rapid7 InsightAppSec, OpenText Fortify WebInspect, Nikto, AppCheck.

How does a DAST tool differ from a SAST tool?

A DAST tool analyzes a running application by mimicking real-world attacks to expose vulnerabilities and weaknesses without accessing source code. On the other hand, a SAST tool analyzes your web application’s source code to identify security flaws early in development. DAST refers to runtime security, whereas SAST focuses on static code analysis.

Can DAST tools scan APIs?

Yes, modern DAST tools, like ZeroThreat, are capable of scanning REST, SOAP, and GraphQL APIs. DAST tools scan every endpoint of APIs by simulating attacks and checking for threats like insecure authentication, misconfigurations, and injection points.

Do DAST tools test for OWASP Top 10 vulnerabilities?

Yes, DAST tools are designed to detect OWASP Top 10 vulnerabilities, such as SQL injection, XSS, broken access control, and security misconfigurations, which are considered critical vulnerabilities within OWASP Top 10 frameworks.

Are DAST tools suitable for DevSecOps workflows?

Yes, DAST tools are highly suitable for DevSecOps workflows as they integrate security testing into the CI/CD pipeline without disrupting development. As a result, you can identify vulnerabilities in real-time environments, ensuring security is continuously assessed.
