What's new in Key Trustee KMS 5.5

  • A Key Administrator role in Cloudera Manager is used for configuring HDFS Data at Rest Encryption. Only a Key Administrator and a Full Administrator can make configuration changes to Java Keystore KMS, Key Trustee KMS, and Key Trustee Server. Configuring HDFS to use Data at Rest Encryption is also limited to the Key Administrator and Full Administrator roles. This allows organizations to keep Key Administrators and Cluster Administrators separate, which is a security best practice.
  • When running Key Trustee KMS in a highly available configuration, Cloudera Manager can automatically generate the load-balancer URL.
