Ensure ElastiCache Redis clusters have encryption at rest enabled
Encryption at rest protects cached data from unauthorized access if the underlying storage is compromised. Uses AWS KMS for key management.
Security Impact
Unencrypted cache data at rest is vulnerable if storage media is compromised, potentially exposing sensitive session or application data.
How to Remediate
Enable encryption at rest when creating new Redis clusters. For existing clusters, create an encrypted snapshot and restore to new cluster.
