What are some effective CSRF protection techniques?

There are several effective techniques for CSRF protection, including using anti-CSRF tokens, SameSite cookies, and checking the HTTP Referer header.

Can you explain how anti-CSRF tokens work?

Anti-CSRF tokens are unique, secret tokens generated by the server and included in forms. When the form is submitted, the server checks if the token matches the one it generated, ensuring the request is legitimate.

What are SameSite cookies and how do they help?

SameSite cookies are a cookie attribute that restricts how cookies are sent with cross-site requests. By setting SameSite to 'Strict' or 'Lax', it helps prevent CSRF attacks by not sending cookies with cross-origin requests.

Are there any other methods to enhance CSRF protection?

Yes, additional methods include implementing user interaction checks, such as requiring re-authentication for sensitive actions, and using Content Security Policy (CSP) to mitigate risks.
