SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pyyaml, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Helping teams find and fix API security issues early and at runtime by combining static OpenAPI audits with dynamic conformance scans and runtime enforcement, reducing exposure to OWASP API Security risks.

Core Features & Use Cases

  • Static API Audit: Analyze OpenAPI v2/v3 specs to surface schema, authentication, transport, and data-exposure issues with remediation guidance.
  • Dynamic Conformance Scanning: Execute runtime scans against staging or running APIs to detect OWASP API Top 10 vulnerabilities and generate machine-readable reports.
  • CI/CD & Runtime Integration: Integrate audits and scans into GitHub Actions or Jenkins pipelines and deploy API Protect as a micro-gateway for contract enforcement.
  • Use Case: Integrate into a CI pipeline so every pull request triggers an OpenAPI audit and prevents merges when the security score falls below the defined threshold.

Quick Start

Run a 42Crunch audit on your OpenAPI file and produce a SARIF or JSON report with authentication tokens if required.

FAQPage Schema
How do I audit an OpenAPI specification for security vulnerabilities?

To audit an OpenAPI specification, you analyze OpenAPI v2/v3 definitions to surface schema, authentication, transport, and data-exposure issues. This process identifies OWASP API Security vulnerabilities and provides remediation guidance before deployment.

Can I run API security scans in a CI/CD pipeline?

Yes, you can integrate API security scans into CI/CD pipelines like GitHub Actions or Jenkins. Every pull request can trigger an OpenAPI audit and prevent merges when the security score falls below a defined threshold.

What is dynamic conformance scanning for APIs?

Dynamic conformance scanning executes runtime scans against staging or production API endpoints. It detects OWASP API Top 10 vulnerabilities and generates machine-readable reports in SARIF or JSON format for remediation workflows.

Do I need a 42Crunch token to perform an OpenAPI audit?

A 42Crunch CLI or API token is optional but required for authenticated scans. You can run a basic audit on your OpenAPI file and produce SARIF or JSON reports, with tokens needed for advanced or authenticated conformance scans.

How does API Protect enforce runtime security contracts?

API Protect deploys as a micro-gateway for runtime contract enforcement. It works alongside static OpenAPI audits and dynamic conformance scans to provide continuous security by validating API traffic against defined specifications.

What formats are supported for API security audit reports?

API security audit reports are produced in SARIF and JSON formats. These machine-readable outputs support security gating in CI/CD pipelines and integrate with remediation workflows to track and fix identified vulnerabilities.
