Securing a REST API requires applying authentication, authorization, input validation, and rate limiting patterns. Strong token handling, RBAC, and secure headers mitigate common vulnerabilities and prevent data breaches across endpoints.

The best way to implement JWT authentication involves robust token handling combined with Role-Based Access Control (RBAC). Enforcing secure token validation and RBAC permissions protects endpoints and ensures only authorized users access specific API resources.

Input validation prevents API injection attacks by sanitizing incoming data before processing. Applying strict validation patterns stops malicious payloads from executing unauthorized commands, preventing data corruption and injection threats across REST, GraphQL, and WebSocket APIs.

You need rate limiting and throttling to protect APIs from DDoS attacks and service disruption. Implementing rate limiting mitigates abuse by restricting excessive request volumes, ensuring API availability and preventing resource exhaustion during malicious traffic spikes.

Yes, you can apply these API security patterns to GraphQL and WebSocket APIs. The approach covers robust authentication, input validation, and data protection across REST, GraphQL, and WebSocket APIs during design, implementation, and review scenarios.
