API security is paramount in modern applications. This guide covers authentication, authorization, and best practices for securing your REST APIs.
JWT (JSON Web Tokens) Authentication
Understand how JWTs work, how to issue and validate them, and best practices for storing tokens. Learn about access and refresh tokens.
OAuth2 Integration
Implement OAuth2 for third-party authentication. Support social logins and API access with proper scopes and permissions.
Role-Based Access Control (RBAC)
Design and implement RBAC systems. Assign roles to users and check permissions at each endpoint to ensure proper access control.
Security Best Practices
Use HTTPS, implement rate limiting, validate input, use CORS properly, and protect against common vulnerabilities like CSRF and SQL injection.
API Key Management
Securely generate, store, and rotate API keys. Implement key rotation policies and monitor API key usage.
Conclusion
Implement these security practices to build APIs that protect user data and prevent unauthorized access. Security is everyone's responsibility!
