Designing Secure RESTful APIs
Implement security best practices for RESTful APIs, including authentication, authorization, rate limiting, and input validation.
APIs Need Strong Security
RESTful APIs are the backbone of modern applications, connecting different services and clients. They expose your backend logic and data to the world, making them prime targets for attackers.
Securing your APIs is not an option; it's a necessity. A single vulnerability can lead to data breaches, service disruptions, or unauthorized access.
Who Are You? API Authentication
Authentication is the process of verifying a client's identity. For APIs, this often means checking if the client has permission to make requests.
- API Keys: Simple secrets sent with requests.
- Tokens (e.g., JWTs): More robust, often used for user authentication flows.
- OAuth 2.0: For delegated authorization (covered in another lesson).
Always use strong, unique credentials and protect them.
