What CGPulse checks
A resource passes this rule when atRestEncryptionEnabled must equal true. Anything else is reported as a finding with the evaluated property value attached as evidence.
How to fix it
Enable encryption at rest to protect stored data from media compromise. In AWS Console: ElastiCache > select cluster > enable At-rest encryption (set at creation). See: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/at-rest-encryption.html
Terraform
resource "aws_elasticache_replication_group" "{name}" {
at_rest_encryption_enabled = true
}
