What CGPulse checks
A resource passes this rule when nodeToNodeEncryptionEnabled must equal true. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Enable node-to-node encryption to protect data in transit within the cluster. In AWS Console: OpenSearch > Domains > select domain > Edit > enable Node-to-node encryption. See: https://docs.aws.amazon.com/opensearch-service/latest/developerguide/ntn.html
Terraform
resource "aws_opensearch_domain" "{name}" {
node_to_node_encryption {
enabled = true
}
}
