What is API Security Testing?

API security testing is the process of testing the endpoints of an application program interface (API) and identifying vulnerabilities and security flaws. API facilitates data exchange between applications, and thus, security testing is crucial because if a hacker breaks API security, he can access sensitive and confidential data.

There are various forms of API security tests. While Static Analysis and Software Composition Analysis look for vulnerabilities in libraries and patterns in your code, Dynamic Analysis searches for potential vulnerabilities by sending active requests to the API and interpreting the response received.

How to do API Penetration Testing?

Here's a step-by-step checklist for performing API Security Testing:

  • Determine the scope to define and list the objectives, scope, desired results, tools, and security solutions to be used. 
  • Scan your APIs to identify all the endpoints, dependencies, and security controls. This will let you outline a baseline context for attack simulations. 
  • Perform Static Analysis and Software Composition Analysis, which identify library vulnerabilities and code patterns. Further, perform Dynamic Analysis which identifies vulnerabilities by sending requests to the API and interpreting the response received.
  • Prepare a detailed report and include the identified vulnerabilities, security gaps, and recommendations to fix them. Lastly, retest and revalidate the APIs to ensure that security recommendations have been completely implemented.
