Any features providing 'Data Level Security'?

[greatfooty]

Another requirement I'm needing to satisfy is 'role based operation upon specific entities'. I can understand some ways I might model that onto each entity which needs it (something like AccessRole.canRead; AccessRole.canWrite; AccessRole.canDelete etc) - but I'm interested to know if there's already anything like this provided by the sculptor DSL?  Or maybe to enable config of role based access to entities and services?
