VIEW RULE IN DATADOG VIEW MISCONFIGURATIONS

Description

ElastiCache Redis replication groups should be encrypted using a customer-managed KMS key rather than the default AWS-managed key. Customer-managed keys provide full control over key rotation policies, access permissions via KMS key policies, and the ability to revoke or disable the key.

Remediation

Create a new replication group with a customer-managed KMS key specified. Existing replication groups cannot have their encryption key changed after creation. For guidance, refer to At-rest encryption in ElastiCache.
