Implementing API Security Testing with 42Crunch
Overview
42Crunch is an API security platform that combines Shift-Left security testing with Shield-Right runtime protection. It provides API Audit for static security analysis of OpenAPI definitions, API Conformance Scan for dynamic vulnerability detection, and API Protect for real-time threat prevention. The platform integrates into CI/CD pipelines and IDEs to identify OWASP API Security Top 10 vulnerabilities before and after deployment.

- Running API instance for dynamic scanning (conformance scan)
- Node.js or Python environment for CLI tooling
Core Concepts
This section covers core concepts for implementing api security testing with 42crunch.
- Ensure all prerequisites are met before proceeding
- Follow the documented workflow steps in sequence
- Record results and any anomalies encountered during this phase
API Audit (Static Analysis)
API Audit performs static security analysis of OpenAPI definitions without requiring a running API. It evaluates the specification against 300+ security checks organized into categories:
Security Score Categories:
- Data Validation: Schema definitions, parameter constraints, response validation
- Authentication: Security scheme definitions, scope requirements
- Transport Security: Server URL schemes, TLS requirements
- Error Handling: Error response definitions, information leakage prevention
Running API Audit via VS Code Extension:
