Hortonworks features comprehensive security that extends across the five security pillars. With this platform approach, HDP enables IT to meet the requirements of Hadoop security better than any other vendor. HDP supports encrypting network traffic as data into and through the Hadoop cluster over RPC, HTTP, Data Transfer Protocol (DTP) and JDBC. Network traffic over each of these protocols can be encrypted to provide privacy for data movement. HDP also satisfies enterprise requirements for security and compliance through encryption for data at rest. HDP supports the capability to encrypt files stored in Hadoop, including a Ranger-embedded open-source Hadoop key management store (KMS). Ranger offers security administrators with the capability to manage keys and authorization policies for KMS.
