REST API Security

REST (Representational State Transfer) APIs are the most common type of web API. Securing REST APIs involves protecting endpoints, validating inputs, and ensuring proper authentication and authorization.

Common REST API Vulnerabilities

• Broken object-level authorization (BOLA)
• Broken authentication
• Excessive data exposure
• Lack of rate limiting
• Mass assignment

Security Best Practices

• Implement proper authentication on all endpoints
• Use consistent authorization checks
• Validate and sanitize all input data
• Implement rate limiting
• Use HTTPS exclusively
• Return appropriate HTTP status codes
• Filter response data to return only what is needed
