WebSockets
- Authentication: Implement authentication mechanisms such as JWT or custom authentication tokens to authenticate clients connecting to WebSocket endpoints.
- Secure WebSocket Protocol: Use secure WebSocket protocols such as WSS (WebSocket Secure) to encrypt data transmission between clients and the WebSocket server, ensuring confidentiality and integrity of data in transit.
- Authorization: Enforce access control policies to restrict access to WebSocket channels or events based on client identities and permissions.
- Input Validation: Validate and sanitize input data received from clients over WebSocket connections to prevent injection attacks and enforce data integrity.
- Rate Limiting: Implement rate limiting to prevent abuse and excessive usage of WebSocket connections by limiting the number of connections or messages per client within a specific time interval.
- Monitoring and Logging: Enable logging and monitoring WebSocket connections, messages, 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.
