We've covered authentication and authorization in depth and also mentioned a few other security measures available in Cassandra or DataStax Enterprise. However, not every deployment will need every security measure in place. What security measures you need depends on the sensitivity of your data and the security characteristics of your deployment. As an application engineer, you likely leave the details of deployment security to your sysadmins, but this table can provide a quick reference to what sort of security measures you should think about:
| Security measure | Vulnerability protected against | Alternative protections |
| Internal authentication & authorization | Direct access to Cassandra cluster ... |
