CIS Control 3: Data Protection

CIS Controls v8 CIS-3.11: Encrypt Sensitive Data at Rest

Encrypt sensitive data held at rest on the servers, applications and databases that contain it. Encryption at the storage layer (server-side encryption) satisfies the minimum for this Safeguard. Further options include encryption at the application layer (client-side encryption), under which access to the storage device alone does not expose the data in plain text.
