What are some good REST API security best practices?

The following are some best practices for REST API security. Authentication and authorization: Ensure strong authentication for API endpoints using OpenID Connect or OAuth standards. Implement RBAC (Role-based Access Control) to prevent unauthorized users from accessing endpoints. Validate User Inputs: Validate every input provided by users before processing it. Prevent Sensitive Data Exposure: Ensure APIs don’t reveal sensitive information like stack traces, error messages, etc. Rate Limiting and Throttling: Limit the number of requests per IP to avoid abuse of the API. Configure CORS: By configuring CORS, you can ensure that only trusted domains connect to the API.

How often should REST API security testing be performed?

API security testing is not a one-time task; it’s a continuous process and should be performed regularly. You can integrate automated security testing tools into the development lifecycle to regularly test APIs for identifying and resolving issues before they are deployed to production.

Can automated security testing tools fully secure APIs?

While automated tools are useful for identifying and resolving common vulnerabilities, combining them with manual testing gives better outcomes. Manual testing offers an in-depth security assessment and can identify more complex or contextual issues that automated tools may not detect.
