API Security Checklist: A Comprehensive Guide

APIs (Application Programming Interfaces) are the backbone of modern software development. They enable applications to interact, exchange data, and provide seamless user experiences. However, as APIs become more prevalent, they also become a prime target for cyberattacks. Securing APIs is crucial for protecting sensitive data, maintaining user trust, and ensuring system integrity. This blog provides a detailed API security checklist that covers best practices to safeguard your APIs from potential threats.

1. Authentication and Authorization

1.1 Use Strong Authentication Mechanisms

• Implement OAuth 2.0 for secure token-based authentication.
• Use JSON Web Tokens (JWTs) to manage session state securely.
