Transparent data encryption

Configure transparent data encrypt (TDE) on sensitive data stored in tables and in configuration files.

cassandra.yaml

The location of the cassandra.yaml file depends on the type of installation:
Package installations /etc/dse/cassandra/cassandra.yaml
Tarball installations installation_location/resources/cassandra/conf/cassandra.yaml

dse.yaml

The location of the dse.yaml file depends on the type of installation:
Package installations /etc/dse/dse.yaml
Tarball installations installation_location/resources/dse/conf/dse.yaml
Note: DataStax recommends encrypting sensitive configuration properties in the dse.yaml and cassandra.yaml files.
