What is API penetration testing?

API penetration testing is a security assessment process that focuses on evaluating the security of Application Programming Interfaces (APIs). Testers simulate real-world cyberattacks on APIs to identify vulnerabilities such as broken authentication, improper access controls, data exposure, and injection flaws. The goal is to uncover weaknesses before malicious actors can exploit them, ensuring that APIs are robust and secure. It typically involves both automated tools and manual testing techniques to thoroughly assess the API's security posture.
