## HiveServer2 authentication

For standard clusters, the recommended setting for HiveServer2 authentication is the default which is none. To enable authentication, we recommend upgrading to an [ESP](../domain-joined/hdinsight-security-overview.md) (Enterprise Security Package) cluster.

## SSL Encryption for HiveServer2

31-
Enabling Hiveserver2 SSL is not recommended for either standard or ESP clusters. SSL is enabled on the gateway instead. [Encryption in transit](../domain-joined/encryption-in-transit.md) can be enabled to encrypt communications among the cluster nodes using [Internet Protocol Security (IPSec)](https://en.wikipedia.org/wiki/IPsec).
