Ensure RDS instance TDE protector is encrypted with BYOK (Use your own key)

HighLevel 2Manual reviewalibaba

Description

TDE with BYOK support provides increased transparency and control, increased security with an HSM-backed KMS service, and promotion of separation of duties. With TDE, data is encrypted at rest with a symmetric key (called the database encryption key). Bring Your Own Key (BYOK) support for Transparent Data Encryption (TDE) allows user control of TDE encryption keys and restricts who can access them and when. Reported as a manual review item: the benchmark audit needs console review or organisational judgement.
