Encrypting Data at Rest
Secure data at rest using encryption mechanisms and key management.
Cloudera clusters can use a combination of data at rest encryption mechanisms, including HDFS transparent encryption and Cloudera Navigator Encrypt. Both of these data at rest encryption mechanisms can be augmented with key management using Key Trustee Server and Cloudera Key HSM.
Before configuring encryption for data at rest, familiarize yourself with the requirements in "Data at Rest Encryption Requirements".
