Cloudera Navigator provides the encryption and key management solution for data at rest. It uses "Key HSM" service which allows "Key Trustee" Server to seamlessly integrate with a hardware security module (HSM) [1]. As part of Key HSM service [2] requirement, we can integrate SafeNet KeySecure HSM appliance [3]. To integrate SafeNet KeySecure HSM appliance, refer the steps here - [4] https://www.cloudera.com/documentation/enterprise/latest/topics/key_hsm_setup.html#concept_nql_dfg_fr Links: [1] https://www.cloudera.com/documentation/enterprise/5-7-x/topics/key_hsm.html#concept_key_hsm [2] Key HSM: https://www.cloudera.com/documentation/enterprise/latest/topics/sg_key_hsm.html [3] https://www.cloudera.com/documentation/enterprise/5-7-x/topics/encryption_prereqs.html#concept_l3r_r54_y5 [4] https://www.cloudera.com/documentation/enterprise/latest/topics/key_hsm_setup.html#concept_nql_dfg_fr ...
