What is CSRF and how does it affect MEAN stack applications?

CSRF stands for Cross-Site Request Forgery. It's a type of attack that tricks the user into executing unwanted actions on a web application where they're authenticated. In a MEAN stack application, if proper CSRF protection isn't implemented, an attacker could exploit the user's session to perform actions without their consent.

How can I protect my MEAN stack app from CSRF attacks?

You can protect your MEAN stack app from CSRF attacks by implementing anti-CSRF tokens. These tokens are unique for each session and must be included in requests that modify data. Additionally, using libraries like csurf in your Express.js backend can help manage these tokens effectively.

Are there any other security measures I should consider?

Yes, besides CSRF protection, consider implementing CORS policies, input validation, and using HTTPS to secure data in transit. Regularly updating your dependencies and using security headers can also enhance your application's security.

What are some common vulnerabilities in MEAN stack applications?

Common vulnerabilities include SQL injection, XSS (Cross-Site Scripting), and improper authentication. It's crucial to regularly audit your code and use security best practices to mitigate these risks.
