How can I ensure my web application is protected from CSRF attacks?

Answer

To protect your web application from CSRF (Cross-Site Request Forgery) attacks, you should implement anti-CSRF tokens in your forms and verify these tokens on the server side.

<!-- BEGIN COPY / PASTE -->
    &lt;form method="post" action="/submit"&gt;
      &lt;input type="hidden" name="csrf_token" value="&lt;?php echo $_SESSION['csrf_token']; ?&gt;"&gt;
      &lt;!-- Other form fields --&gt;
      &lt;button type="submit"&gt;Submit&lt;/button&gt;
    &lt;/form&gt;
    <!-- END COPY / PASTE -->

Additional Comment:

Generate a unique CSRF token for each session and store it in the user's session data.
Ensure the token is included in every state-changing request (e.g., POST, PUT, DELETE).
Verify the token on the server side before processing the request to confirm its validity.
