Step-by-Step Guide to Testing APIs for Security Vulnerabilities
By Amit Kumar
What is API Security Testing?
API Security Testing is a critical discipline in modern cybersecurity that focuses on identifying vulnerabilities in Application Programming Interfaces (APIs). As organizations increasingly rely on APIs to connect services, securing these interfaces has become paramount.
Common API Vulnerabilities
BOLA/IDOR
Broken Object Level Authorization allows accessing resources by manipulating object identifiers.
Broken Authentication
Weak authentication mechanisms enable unauthorized access.
Excessive Data Exposure
APIs expose more data than necessary.
Injection
SQL, NoSQL, Command injection through unvalidated input.
Essential Tools
Burp Suite
HTTP proxy and vulnerability scanning
Postman
API development and testing
OWASP ZAP
Open source web app scanner
