Role-Based Access Control (RBAC) is a powerful method for managing permissions based on user roles within an application. By combining RBAC with JWT (JSON Web Token) authentication, you can control access to specific resources, ensuring that only authorized users can access or modify certain parts of your application.
In production environments, protecting sensitive data is a critical priority for any application, and securing database connections is fundamental to safeguarding user information and ensuring compliance. For Node.js applications, implementing robust database security involves multiple layers, including authentication, encryption, role-based access control, and secure connection management. This guide covers essential strategies for securing your database in Node.js, discussing secure connection setup, data encryption, and best practices for maintaining a strong security posture.
Two-Factor Authentication (2FA) is an extra layer of security that requires not only a password and username but also something that only the user has on them, typically a one-time code generated by an app like Google Authenticator. This guide walks you through implementing 2FA in a Node.js application using TOTP, Google Authenticator, and otplib.
