conducting-api-security-testing
Conducts security testing of REST, GraphQL, and gRPC APIs to identify vulnerabilities in authentication, authorization, rate limiting, input validation, and business logic. The tester uses the OWASP API Security Top 10 as the testing framework, combining Burp Suite interception with Postman collections and custom scripts to test endpoint security at every privilege level. Activates for requests involving API security testing, REST API pentest, GraphQL security assessment, or API vulnerability testing.

# Conducting API Security Testing
## When to Use
- Testing API endpoints for authorization flaws, injection vulnerabilities, and business logic bypasses
- Assessing the security of microservices architecture where APIs are the primary communication method
- Validating that API gateway protections (rate limiting, authentication, input validation) are properly enforced
- Testing third-party API integrations for data exposure and insecure configurations
- Evaluating GraphQL APIs for introspection disclosure, query complexity attacks, and authorization bypasses
**Do not use** against APIs without written authorization, for load testing or denial-of-service testing unless explicitly scoped, or for testing production APIs that process real financial transactions without safeguards.
## Prerequisites
- API documentation (OpenAPI/Swagger, GraphQL schema, Postman collection) or application access to reverse-engineer the API
