RESTful APIs
- Authentication: Use authentication techniques to confirm the legitimacy of clients gaining access to the RESTful API endpoints, such as OAuth 2.0, JWT (JSON Web Tokens), or API keys.
- Authorization: Enforce access control policies based on roles, permissions, or scopes to determine what actions authenticated users or clients are allowed to perform within the API.
- HTTPS Encryption: Use HTTPS with TLS/SSL encryption to secure data transmission between clients and the RESTful API server, ensuring confidentiality and integrity of data in transit.
- Input Validation: Validate and sanitize input data received from clients to prevent common security vulnerabilities such as injection attacks (e.g., SQL injection, XSS).
- Rate Limiting: Implement rate limiting to prevent abuse, DoS attacks, and excessive usage of resources by limiting the number of requests per client or IP address within a specific time interval.
- Monitoring and Logging: Enable logging and monitoring of API traffic, errors, and security events to detect and respond to security incidents in real-time.
API Gateway Security in System Design
A server that serves as a middleman between clients and backend services is known as an API gateway. It serves as a hub through which clients (like web or mobile applications) can access information, features, or other services offered by different backend systems without having to communicate with them directly. A number of important factors need to be taken into account when building an API gateway’s security features within a system in order to protect the gateway and the underlying services it communicates with.
