Hi Ajay,
Have a look here :
https://docs.datastax.com/en/cassandra/1.2/cassandra/security/secureSSLNodeToNode_t.html
You can configure for DC level Security:
Procedure
On each node under sever_encryption_options:
- Enable internode_encryption.
The available options are:
- all
- none
- dc: Cassandra encrypts the traffic between the data centers.
- rack: Cassandra encrypts the traffic between the racks.
regards
Neha
