What are the best security practices for a MEAN stack application?

To secure a MEAN stack application, consider implementing the following practices: 1. Use HTTPS to encrypt data in transit. 2. Validate and sanitize user inputs to prevent injection attacks. 3. Implement authentication and authorization using JWTs. 4. Regularly update dependencies to patch vulnerabilities. 5. Use environment variables to manage sensitive information.

How can I protect against SQL injection in my application?

To protect against SQL injection, always use parameterized queries or ORM libraries that handle query building for you. Avoid concatenating user inputs directly into SQL statements.

What tools can I use to test the security of my MEAN stack app?

You can use tools like OWASP ZAP, Burp Suite, and Postman for security testing. They help identify vulnerabilities and assess the security posture of your application.

Are there any specific libraries you recommend for authentication?

Yes, for authentication in a MEAN stack, consider using Passport.js for handling various authentication strategies and bcrypt for hashing passwords.
