Dynamically Testing APIs: Top 6 DAST Tools

Application Programming Interfaces (APIs) are everywhere today. They’ve advanced so quickly that we are yet to have a good grasp on ways to test them. APIs allow different software components to communicate with each other irrespective of the language used on either end. Most of the time, APIs are used for developing web applications. This is where DAST comes in. Dynamic application security testing (DAST) is a great way to test web applications and can work wonders for testing APIs. In this article, we will discuss how API testing can be done using DAST tools and also list six of the best DAST tools for API testing.

Is DAST only for web applications?

No, the scope of DAST is not limited to web applications. It is useful for testing APIs as well. API testing using DAST is a great way to test APIs as it can detect vulnerabilities that static analysis or conventional API testing tools might not be able to find.

Benefits of DAST

Some of the benefits of using DAST for API testing include:

  • Detection of vulnerabilities that might not be found through other means of testing
  • Ability to test APIs while they are running and get a better understanding of their response to real-time attacks.
  • Greater visibility into the inner workings of an API

How does a DAST tool work?

DAST tools work by dynamically scanning the application while it’s running. This is done by sending all sorts of malicious requests to the application and analyzing the responses. The tool then looks for vulnerabilities that might be present in the code or in the way the application is responding to the requests. This gives testers a better idea of how the application works and what kind of vulnerabilities a hacker can find. Additionally, DAST tools can be used to test the security of APIs since APIs are used widely in web applications (irrespective of the platform).

Top 6 DAST tools for API testing

Now that we know what DAST is and some of its benefits, let’s take a look at some of the best DAST tools for API testing.

Here are six of the best DAST tools for API testing:
