API penetration testing encompasses the entire process of identifying vulnerabilities and creating secure endpoints in your APIs. API abuse is one of the most prevalent application risks, and it may wreak havoc on the regular operation of any digital enterprise. If deployed APIs are not thoroughly tested for security, problems such as data leakage, unauthorized access, and parameter tampering might develop.
The goal of an API penetration test is to find ways to exploit an API’s functions and methods and circumvent its authorization and authentication mechanisms. At the very least, an API penetration test includes checks for the following vulnerabilities (included in the OWASP API Security Top 10):
-
Broken Object Level Authorization
-
Broken User Authentication
-
Excessive Data Exposure
-
Lack of Resources & Rate Limiting
-
Broken Function Level Authorization
-
Mass Assignment
-
Security Misconfigurations
-
Injection
-
Improper Assets Management
-
Insufficient Logging & Monitoring
