Securing the Key Management System (KMS)
Cloudera provides the following Key Mangement System (KMS) implementations: Ranger KMS with database, Ranger KMS with HSM, Ranger KMS with Key Trustee Server, and Ranger KMS with Key Trustee Server and Key HSM. You can secure Ranger KMS using Kerberos, TLS/SSL communication, and access control lists (ACLs) for operations on encryption keys.
Cloudera Manager supports wizard-driven instructions for installing both Ranger KMS with a database and Ranger KMS with KTS.
