Starting from Symfony 2.4, the Security component is divided into four smaller
sub-components which can be used separately:

``symfony/security-core``
It provides all the common security features, from authentication to
authorization and from encoding passwords to loading users.

``symfony/security-http``
It integrates the core sub-component with the HTTP protocol to handle HTTP
requests and responses.

``symfony/security-csrf``
It provides protection against `CSRF attacks`_.

``symfony/security-acl``
It provides a fine grained permissions mechanism based on Access Control Lists.
