-Amazon MSK provides data encryption options that you can use to meet strict data management requirements. The certificates that Amazon MSK uses for encryption must be renewed every 13 months. Amazon MSK automatically renews these certificates for all clusters. It sets the state of the cluster to `MAINTENANCE` when it starts the certificate-update operation. It sets it back to `ACTIVE` when the update is done. While a cluster is in the `MAINTENANCE` state, you can continue to produce and consume data, but you can't perform any update operations on it.
