Best Practices for Securing APIs with Authentication and Authorization

Securing APIs with authentication and authorization is crucial for protecting sensitive data and ensuring only authorized users access resources. Authentication verifies the identity of users, typically through tokens, passwords, or keys. Authorization determines what actions authenticated users are allowed to perform. Best practices include using HTTPS for secure communication, implementing OAuth or JWT for authentication, enforcing least privilege access, regularly auditing permissions, and employing rate limiting and throttling mechanisms to prevent abuse. Additionally, ensure proper input validation, use encryption for sensitive data, and regularly update security measures to stay ahead of emerging threats.
