A comprehensive checklist of security countermeasures for designing, testing, and releasing secure APIs.
API Security Checklist is a comprehensive guide that outlines essential security measures for API development across authentication, access control, input validation, and monitoring. It helps developers prevent common vulnerabilities like injection attacks, broken authentication, and data exposure by providing actionable checkpoints throughout the API lifecycle.
API developers, security engineers, and DevOps teams who design, build, or maintain web APIs and need a structured approach to security implementation.
It consolidates industry best practices into a single, actionable checklist that’s available in multiple languages, making it accessible for global teams to systematically improve API security without reinventing solutions.
Checklist of the most important security countermeasures when designing, testing, and releasing your API
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Spans the entire API lifecycle from authentication and input validation to monitoring, ensuring no critical area is missed, as evidenced by detailed sections on Authentication, Processing, and CI/CD.
Available in over 20 languages due to community contributions, making it a globally relevant resource for diverse development teams, as shown in the README's translation list.
Provides concrete, checkbox-style items like using HTTPS with TLS 1.2+ and removing fingerprinting headers, offering clear steps that developers can directly implement.
Advocates for using standards like OAuth and avoiding custom implementations, reducing security risks from homemade solutions, as highlighted in the Authentication and OAuth sections.
Lacks code snippets or detailed examples for checkpoints, forcing developers to seek external resources to actually implement security measures, which can slow down adoption.
As a static document, it doesn't auto-update with new vulnerabilities or integrate with tools, requiring manual effort to apply and maintain, which can be time-consuming for fast-evolving projects.
The extensive list includes advanced topics like GraphQL-specific security and zero trust architecture, which might overwhelm teams building simple or internal APIs.
