 Once your application is complete, or even before that you'll want to deploy it.
 There are a few things you should do when deploying a CakePHP application.
 
+Check your security
+===================
+
+If you're throwing your application out into the wild, it's a good idea to make
+sure it doesn't have any leaks. Check the :doc:`/core-libraries/components/security-component` to guard against
+CSRF attacks, form field tampering, and others. Doing :doc:`/models/data-validation`, and/or 
+:doc:`/core-utility-libraries/sanitize` is also a great idea, for protecting your
+database and also against XSS attacks. Check that only your `webroot` directory 
+should be publicly visible, and that your secrets (such as your app salt, and
+any security keys) are private and unique as well!
