How can I enhance security in my MERN application?
To enhance security in your MERN app, consider implementing JWT for authentication, using HTTPS, and validating user inputs.
What is JWT and how does it work?
JWT, or JSON Web Token, is a compact, URL-safe means of representing claims to be transferred between two parties. It allows you to verify the sender's identity and ensure the message wasn't changed.
Are there any specific libraries you recommend for securing a MERN app?
Yes, I recommend using libraries like Helmet for securing HTTP headers, bcrypt for password hashing, and express-rate-limit to prevent brute-force attacks.
How can I protect my MongoDB database?
You can protect your MongoDB database by enabling authentication, using IP whitelisting, and ensuring your database is not exposed to the public internet.
