Aurora/RDS cluster storage is not encrypted at rest

What this check finds

The DB cluster has StorageEncrypted=false, so cluster volumes, automated backups, snapshots, and replicas are stored unencrypted. Anyone able to access the underlying storage or a snapshot can read the data. Cluster-level encryption is not reflected in per-instance checks.

Passing looks like: Aurora/RDS cluster encrypted at rest.

How to fix it

Encryption cannot be enabled in place. Take a snapshot, copy it with a KMS key to produce an encrypted copy, and restore a new encrypted cluster, then cut over.

Compliance controls it is evidence for

A failing result counts against these controls in KloudLytics; a passing one is evidence towards them. How compliance mapping works

Checked on every scan

KloudLytics runs this check each time it scans a connected AWS account, through a read-only role, and lists every affected resource with its region. On Pro and Business a fix is written for the specific resource rather than the general case above. The exact access it needs
