Things to improve
=================

* ALLOWED_HOSTS - do not use * - introduce parameters
* CACHES - configure caching engine - is it not allowed by default?
* SESSION_ENGINE - change it from signed cookie to something else
* policy files - look into these files and think of further configuration/parametrisation
