The application is responsible for defining permissions and using them
to protect objects / methods.  Five enables using the stock
zope.security stuff to define permissions in ZCML, and to associate them
with interfaces / attributes.  See:

 - $ZOPE_HOME/lib/python/Products/Five/permissions.zcml

 - $ZOPE_HOME/lib/python/zope/security/meta.zcml

 - $ZOPE_HOME/lib/python/zope/app/security/meta.zcml

GenericSetup is responsible for capturing the "placeful" mapping of
permissions to roles (as set on the ZMI "security" tab).
