Much of what we have covered deals in some way or another with access, but we have kept it out of our discussions to keep things more to the point. However, access control is an immensely important topic for Drupal development because it has implications in almost everything we do. So, for this purpose, we have a chapter dedicated to it in which we will cover the most important things you need to know in order to keep your application secure.
