How secure are your interfaces?

API penetration test

API penetration test

An API penetration test is a type of security test that attempts to bypass the security measures of an application programming interface (API) and uncover vulnerabilities. Various techniques and methods are used to examine the API for vulnerabilities and security gaps and to check whether it is possible, for example, to access sensitive data or systems. The purpose of an API penetration test is to uncover and eliminate vulnerabilities in the security of the API before they can be exploited by attackers.

Why should your company carry out an API pentest?

APIs are interfaces that are now often the basis for many different applications. One and the same API can be addressed by web applications, smartphone apps and desktop clients or used for integration into other programmes. This deep integration can make an API an extremely lucrative target for attackers.

In our API penetration test, we orientate ourselves in particular on the OWASP API Security Top 10 and examine their APIs for previously unknown vulnerabilities. Authorisation concepts in particular are being put to the test.

Black Box - Little to no information

Penetration test of the API without a previously registered user or as a normal user. No additional information is available.

Grey Box - Additional initial information

During the API penetration test, we have access to different users who have different levels of authorisation. This allows us to check more quickly whether endpoints that should be reserved for higher-privileged users can be accessed by lower-privileged users.

White Box - Comprehensive information and access to users, source code and logs

The most effective approach: We have access to different users with different rights, as well as to parts of the source code and the logs. This is the most efficient approach as we can gain a comprehensive picture of the security of the API.
