When developing or using APIs, ensuring security is critical to protect data integrity, confidentiality, and availability. Here are key practices to enhance API security:

  1. Authentication & Authorization

    • Implement strong authentication mechanisms like OAuth 2.0 or JWT Token.
    • Use role-based access control (RBAC) to restrict unauthorized access.

  2. Data Encryption

    • Encrypt data in transit using TLS 1.2 or higher.
    • Encrypt sensitive data at rest with AES-256.

  3. Rate Limiting & Throttling

    • Prevent abuse by limiting request rates.
    • Use tools like API GW (API Gateway) to enforce policies.

  4. Input Validation

    • Sanitize all user inputs to avoid injection attacks.
    • Validate data formats and lengths rigorously.

  5. Secure Headers

    • Set HTTP Strict Transport Security (HSTS) and Content Security Policy (CSP) headers.
    • Disable debug mode and use secure cookies.
