Apache Cassandra
TMA-CASSANDRA-5.1
Inter-node Encryption
HighLevel 1Automatedcassandra
Description
Cassandra offers the option to encrypt data in transit between nodes on the cluster. By default, inter-node encryption is turned off. Checks /etc/cassandra/cassandra.yaml (package install; SKIP when it does not exist). Acceptable values are all, dc or rack.

How it is fixed
Fix method: Guidance or infrastructure patch
Build keystores/truststores, set server_encryption_options.internode_encryption: all in cassandra.yaml and rolling-restart all nodes.
