What is an API?An API (Application Programming Interface) is a data exchange used by web applications to transfer information between systems. APIs are used by programmers in mobile applications and web applications.
Why is API penetration testing important?A poorly secured API can open security gaps and vulnerabilities, not just for the API but for any other system that it is connected to as well.
Who needs API penetration testing?Any business that uses mobile or web applications that have an API back-end should have periodic API penetration testing. API security is an essential component of application security.
What are the benefits of Pen Testing?Penetration testing helps proactively identify vulnerabilities and attack vectors within systems and web applications that could be leveraged by adversaries.
How do you perform an API penetration test?API pen testing begins with scoping to understand the client's infrastructure, software stack, and API documentation. Once a project is properly scoped pen testers typically begin with manual testing methods to gain a clear understanding of how the APIs work. From here, testers use automated testing tools for further research. When a suspected vulnerability is found, testers work on exploiting the vulnerability to see how it could impact the confidentiality, availability, and integrity of the systems.
