SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of securing modern APIs by providing a structured, multi-phase testing framework that ensures vulnerabilities are identified and mitigated during the development lifecycle.

Core Features & Use Cases

  • Multi-Layered Testing: Covers critical security domains including authentication, authorization, rate limiting, and input validation.
  • GraphQL & REST Support: Provides specific workflows for both traditional REST endpoints and modern GraphQL schemas.
  • Use Case: Use this workflow to perform a security audit on a new microservice before deployment to ensure that IDOR vulnerabilities, improper rate limiting, and injection flaws are caught and remediated.

Quick Start

Use the api-security-testing skill to initiate a full security audit on the target API endpoint.

FAQPage Schema
How do I perform a security audit on a REST API to find IDOR vulnerabilities?

To perform a REST API security audit and find IDOR vulnerabilities, use a systematic multi-phase testing framework that maps data flows and checks authentication, authorization, and input handling. This approach identifies improper access controls before deployment.

Can I test GraphQL APIs for authentication and rate limiting flaws?

Yes, you can test GraphQL APIs for authentication and rate limiting flaws using specific security workflows designed for modern schemas. The assessment systematically maps data flows to identify common injection and rate-limiting vulnerabilities.

What is the best way to map data flows for bug bounty hunting on web APIs?

The best way to map data flows for bug bounty hunting on web APIs is to execute a structured security assessment that adheres to defined security checklists. This ensures systematic identification of authorization and input handling vulnerabilities.

Does API security testing require manual verification of automated findings?

Yes, API security testing requires manual verification of automated findings to ensure accuracy. The process combines automated systematic assessments with manual checks to validate suspected authentication, authorization, and injection flaws.

How do I check for input validation and injection flaws in microservices?

To check for input validation and injection flaws in microservices, run a full security audit on the target API endpoint. The multi-layered testing framework evaluates input handling to catch and remediate vulnerabilities during the development lifecycle.

When do I need a multi-phase testing framework for API vulnerability assessments?

You need a multi-phase testing framework for API vulnerability assessments when securing modern APIs before deployment. It provides a structured approach to identify and mitigate authentication, authorization, and rate limiting flaws across REST and GraphQL endpoints.
