API Vulnerability Assessment
API Vulnerability Assessment
Focused security testing for RESTful APIs, GraphQL endpoints, and microservices. Our API penetration testing identifies authentication flaws, authorization bypasses, and API-specific vulnerabilities.
We test API endpoints for common vulnerabilities including broken authentication, insecure direct object references, mass assignment, rate limiting issues, and insecure data transmission. Our assessments cover both public and private APIs.
Our specialized API testing approach validates security controls, tests for business logic flaws, and ensures proper implementation of security best practices in modern API architectures.
Steps We Take
Our comprehensive 6-step approach ensures thorough security assessment of your API infrastructure
API Discovery & Documentation Review
We identify all API endpoints, review API documentation (OpenAPI/Swagger), and map the API structure. This includes analyzing authentication mechanisms, rate limiting, and API versioning strategies.
Authentication & Authorization Testing
Comprehensive testing of API authentication methods including API keys, OAuth 2.0, JWT tokens, and session management. We test for token manipulation, authorization bypasses, and privilege escalation vulnerabilities.
Input Validation & Injection Testing
We test API endpoints for injection vulnerabilities including SQL injection, NoSQL injection, command injection, and LDAP injection. Input validation weaknesses and parameter manipulation are assessed.
Rate Limiting & DoS Testing
Assessment of API rate limiting mechanisms, resource exhaustion attacks, and denial-of-service vulnerabilities. We test for API abuse, brute force attacks, and request flooding.
Data Exposure & Privacy Testing
Testing for sensitive data exposure in API responses, error messages, and logs. We identify information disclosure vulnerabilities, excessive data exposure, and privacy violations.
Business Logic & Security Misconfiguration
We assess API business logic for flaws including mass assignment, insecure direct object references, and workflow bypasses. Security misconfigurations and default settings are tested.
