HortonWorks Hadoop encryption tools and data security

Question

Can someone please tell me that which are the tools available for data security and encryption purpose supported by Hortonworks distribution of Hadoop? I need this so that I can encrypt my data file present in HDFS and Hive.

Answer 1

There are many tools available for encrypting and securing data. Apache Knox and Apache Ranger are one of them.

Let's take a look at both of them.

The Hortonworks Data Platform (HDP) supports Apache Knox which is a REST Gateway that provides perimeter security in the form of authentication and access control.

Additionally, the Hortonworks Data Platform version 2.2 brings support for Apache Ranger, which is a policy-based security framework for defining policies to control access to files, folders, databases, tables, or columnns. This works with HDFS, Hive, HBase, Storm as well as Knox.

To learn more about security at Hortonworks Data Platform, take a look at this pdf: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.1/bk_security/bk_security.pdf

Hope this will help!
